Project Description
LHCb is a particle physics experiment operating at the Large Hadron Collider (LHC) at CERN. It is the
world’s leading flavour physics experiment and has a unique capability to explore physics beyond the
Standard Model (SM). Flavour observables are sensitive to virtual quantum loops, which can be mediated
by particles with masses significantly heavier than those that can be produced directly. LHCb’s main aim
is to search for new physics beyond the SM through precision tests of matter anti-matter asymmetries
(CP violation) and rare decays in heavy-quark flavour physics. The experiment also has world-class
programmes related to lepton-flavour violation, forward electroweak, and QCD measurements. The LHCb
Upgrade project will increase the reach of LHCb’s programme and widen the physics profile to that of a
general purpose detector in the forward region, covering a kinematic regime inaccessible to ATLAS and
CMS.
The UK groups will provide major components of the upgrade of the VELO (Vertex Locator), the most
precise vertex detector at the LHC, and LHCb’s unique RICH (Ring Imaging Cherenkov) particle
identification (PID) system. These systems are crucial to the widely recognised success of the current
LHCb experiment. A programme of work on development of the LHCb high level trigger algorithm
development complements this work. These contributions are the key deliverables. The purpose of this
project is the construction and installation of these elements.
The upgraded experiment will be installed during the LS2 shutdown of the LHC, planned for 2019-21.
LHC operations are expected to start in April 2021. The readiness of the detectors for the LHC start is the
principal aim of the project.

Third Progress Report covering period 13th June 2014 – 15th December 2015.
Executive Summary
The revised LHC schedule has been confirmed, delaying the start of operations by one year.
Expenditure forecasts and milestones have been updated appropriately.
The Consolidated Grant for Particle Physics has been announced, this has reduced the available staff
funding for the project by £101k.
Good progress has been made on the VELO, notably the EDR for micro-channel plates has taken
place. Similarly the RICH project is proceeding well, the contract for the MaPMTs (single largest order in
the full project) has been signed. The main concerns in the project are discussed below or commented
in the risk register.
UK Funding Situation
-Desirable Additions. This text is largely unchanged from the previous report
A statement of interest for the LHCb upgrade was submitted in May 2013 and a full proposal in August
2013. Limited bridging funds were awarded for the period January – September 2014. A descoped
proposal was approved in August 2014 by science board (SB) with two scenarios recommended
depending on the available funding in STFC.
In this SB recommended a baseline programme with desirable additions, however due to capital
limitations STFC was not able to award the capital elements of the additions at that time. Therefore a
work plan document was submitted in November 2014 to meet the lower award value without the
additions, with most details of the baseline grant being clarified by the start of 2015. The JeS grant
starting certificate was received on 21st April 2015. Project posts and equipment grants were awarded
for the period October 2014 – April 2020. Ring-fenced consolidated grant effort was awarded for the
period April 2014-April 2020.
LHCb UK believes the desirable additions would be of great benefit to the project. These elements
approved by Science Board but for which funding is not yet available are: additional capital funding for
WP1 of £199k and for WP2 of £356k. The funding decision on these is anticipated after the
Comprehensive Spending Review, hence we assume we will hear before the next OSC meeting, and
we urge the OSC to strongly support these.
We were informed at the last OSC that contingency funds are not expected to be available for this
project.
-Consolidated Grant 2015-2019 Outcome.
The ring-fenced effort in the project was subject to a cap on FTE / year on core staff, determined by the
grants panel. Risks to the project exist for a small number elements for which the UK has responsibility
in the TDRs and no international partner has been found. The collaboration was requested to submit
bids for additional consolidated grant effort necessary for the project completion as part of the
consolidated grant review.
Fractions of ring-fenced consolidated grant positions (including the FTE equivalent of the agreed
commissioning costs) at five UK institutions were not awarded. As instructed in the guidelines no cases
for the ring-fenced fractions of posts was submitted. We are grateful to the office for reinstating the most
problematic of these posts, a 50% per year ring-fenced position. Other posts removed were ring-fenced
at the 20% level/year or below and we believe we can adjust for this without major degradation to the
project. We detail the effect on individual posts below. The final outcome corresponds to a reduction in
the funding of this project by a further £101k.
The non-award of support for Tizick, removes Warwick's hardware contribution to the project.
Page 2 of 13
OFFICIAL SENSITIVE
LHCb Upgrade OsC PAR 1(14)
The core post of E. Rodrigues (Manchester) was not awarded. This post was the only effort for
WP2.1.2, VELO Silicon readout and reconstruction software. Consequently milestones and deliverables
for this project element have been removed. The UK will attempt to still continue to contribute in this
area on a best effort basis through students and synergies with PDRA work on the current detector
where a UK responsive RA (J. Harrison, Manchester) is currently the software co-ordinator.
The core post of A. Richards (Imperial) was not awarded. The post had effort on WP3.2 (Trigger) for the
further development of multivariate analysis methods in the trigger. An attempt will be made to find this
effort through flexibility of core staff awarded to other projects at Imperial but there is a significant risk
that this is not possible. If that turns out, the involvement in the LHCb trigger will be scaled back.
The core post of Ilya Tsurin (Liverpool) was not awarded. For the LHCb upgrade: Tsurin provided the
mask design and was pixel engineer (WP 2.3.1) for the sensor tiles and would perform the testing of the
bump-bonded pixels to produce a qualified pixel-tile assembly for delivery to Manchester. Although the
development and design of LHCb pixels has been retained and will be delivered (as it was almost
complete) there is now no Liverpool effort allocated for the QA necessary test the tiles prior to
assembly. This represents a risk in the production chain.
Additional fractional post funding was awarded for work on the VELO HV system (M.Perry,
Manchester), where hardware costs will be born from central (CERN) project funds and a collaboration
with Moscow state university has started. We are grateful for this award that will allow the UK to fulfil its
TDR commitment in this area.
The high priority areas for additional awards of the VELO vacuum feedthroughs and core computing
contributions were not awarded. The international project management has been fully informed of the
outcome. Negotiations are underway between CERN and a non-UK institution to cover the critical path
development work on the VELO vacuum feedthroughs.
The CG round was particularly hard in respect of computing posts. Some key existing LHCb computing
posts were not awarded notably at Manchester, Imperial and Liverpool. All of these were material to the
upgrade in one way or another (Ganga support, distributed computing support and the National
Computing Board Rep). In additions, several small fractions of new posts were bid for to augment the
computing manpower, but all of these were also not funded. This means that at present the computing
manpower situation for LHCb is a high-risk element of the upgrade project. The LHCb management
and computing management are fully aware.
-Internal Finance/management arrangements
Equipment funds were awarded through Manchester, Oxford, RAL. A collaboration agreement between
all institutes to cover reimbursement of equipment expenses has been produced.
A memorandum on VAT issues has also been produced, with input from advisors in all institutes.
The VAT-free position of the primary project equipment costs is dependent on the ownership of the
detector being gifted to CERN. CERN have agreed to this position and STFC replied that it did not have
any objection.
Alison Fletcher has replaced Deborah Lea as the project officer (20% post).
LHC Schedule
The revised LHC schedule discussed at the last OSC was approved by CERN in September 2015.
The long shutdown 2 (LS2), in which the LHCb upgrade will be installed, will start at the end of 2018.
The shutdown will last two years. Operations of the upgraded detector will start in early 2021. This is a
delay of 12mths with respect to the awarded project. We are proceeding as discussed at the last OSC.
Page 3 of 13
OFFICIAL SENSITIVE
LHCb Upgrade OsC PAR 1(14)
We assume that a zero-cost extension on project supported posts is permitted until April 2021. Institutes
have thus been instructed that they can reprofile future costs to take account of the schedule delay.
However, as most posts have already been hired in practice there is often limited freedom to do this.
We assume that extensions to those project supported posts deemed critical will be financed through
two mechanisms. CERN have indicated that savings in M&O B contributions to LHCb during LS2 could
indeed be utilised for this purpose and this (item 1.1(0) of the feedback from the previous OSC) is now
our baseline plan. The project has working allowance but does not have an allocated contingency. A
component of the working allowance has been profiled to partially cover the costs of the delay, indeed a
CERN schedule delay was always our highest rated project risk. A first working allowance profile has
been circulated with this documentation in the finance spreadsheet.
The consolidated grant ring-fence on this project runs until April 2020. We will discuss with STFC how
best to handle the ring-fence request for the additional year of the programme.
A revised set of milestones for the project has been produced and circulated with this documentation.
These are agreed with the international experiment and match with those circulated recently to the
CERN LHCC, though our UK milestones are more detailed.
A revised equipment spend profile for the project has been produced and circulated with this
documentation. Spend in this current financial year is notably low as many design reviews have been
pushed back.
WP1 RICH
The design of the LHCb RICH systems has been documented in the LHCb Upgrade Particle
Identification TDR CERN/LHCC 2013-022 LHCb TDR 14. Subsequently work has continued on
producing prototypes and preparing designs for Engineering Design Reviews (EDRs).
WP1.1 RICH Simulation, optimisation and reconstruction
There are no issues associated with the simulation and reconstruction code for the RICH Upgrade. The
optics and photon detector layouts for RICH1, including all modifications required by the engineering
constraints, have been determined. Milestones M1.1.1A and M1.1.1B have thus been met. Further
small modifications to the simulation will be made when PRR engineering details are finalized. As
previously reported, the code is fully integrated into the LHCb Upgrade simulation, and milestones
M1.1.2A and M1.1.3A have been completed. Work on providing a more complete simulation of the
Boole digitisation code which simulates the detector electronics readout is progressing well. A fully
functional implementation of the reconstruction code for the Upgrade is available and will evolve in the
years up to data taking.
WP1.2 RICH Photon Detectors
As previously reported, the flat-panel Hamamatsu R11265 and H12700 MaPMTs have been fully
qualified for use in the LHCb RICHes, completing milestones M1.2.1.A.and M1.2.1.B and deliverable
D1.2.1. The photon detectors have been successfully operated in a second test beam campaign using a
readout employing the penultimate submission of the CLARO readout chip. Four elementary cells (ECs)
have been employed, each with 2x2 MaPMTs, including cooling and two prototype readout boards per
EC. This represents a first system test with prototype electronics and the resolutions and photon yields
are largely as expected. The Edinburgh Group shares the task at the 50% level of MaPMT testing and
EC assembly and verification with Italian partners Padua and Ferrara (WP1.2.2, WP1.2.3). A work-plan
has been agreed on the task sharing and testing sequence. The Hamamatsu delivery schedule has also
been agreed (see below), which has introduced a minor 4 months delay on the photodetector
milestones. The Edinburgh (and also Padua) MaPMT test centres will be ready for operation before the
first tube deliveries.
A major LHCC milestone was achieved in November 2015, namely the successful tendering and
Page 4 of 13
OFFICIAL SENSITIVE
LHCb Upgrade OsC PAR 1(14)
acceptance of contract with Hamamatsu for the supply of 3100-off R13742 (formerly R11265)
customized MaPMTs and 450-off R13743 (formerly H12700) customized MaPMTs. The tender did not
exceed that estimated from the TDR (which was 4.9 MChF including mu-metal shielding) - the UK
remains committed to its MoU share of £1.285M. Currency fluctuations of the Yen over the coming
years remain a risk to the project; alternatively any potential savings from the same can facilitate
purchase of unfunded RICH items.
WP1.3 RICH Detector Mechanics and Optics
The RICH1 geometry and optical arrangements have been optimised following rigorous simulations of
performance. The RICH1 mechanical design is now well underway and the phase of preparing detailed
engineering CAD drawings is proceeding rapidly. To this end an integrated CAD design model defines
the constraints for the sub-component boundaries.
The elementary cells have been designed in columns, and housed inside the existing RICH1 magneticshielding iron structures. The column arrangement, installation and extraction mechanisms for the
photon detectors (WP1.3.1) remains a crucial design issue. This design has been guided by the synergy
with RICH2 for the cooling strategy, cable routing and mountings for the electronics cards, and here the
UK design team is working in close collaboration with Italian and CERN colleagues. There has been
considerable progress in the mounting scheme for MaPMT columns into RICH1. The baseline is the
“open” geometry where columns of MaPMTs can be removed/inserted individually (reducing
significantly the access time required for replacement in case of a fault). The routing of cables and
cooling pipes is now proceeding according to this scheme.
The design of the gas enclosure (WP1.3.4), which is the structural frame to which all mirrors and
windows are attached, is well advanced, and is now awaiting details of the interfaces for bolt-hole
locations. The RICH1 exit window (carbon fibre skin/ foam core) and all seals will be manufactured in
house and the designs are almost complete (WP1.3.3). The current RICH1 entrance seal to the
beampipe and VELO will be reused if it doesn’t degrade after removal. The EDRs for the individual
RICH1 mechanical components was scheduled for the end of this year, but due to the complex design
of the MaPMT housings and extraction mechanism, plus this design is crucial to performance, the EDR
milestone has been delayed by 6 months until July 2015. The likely scenario is that the EDR for RICH1
and RICH2 MaPMT housings will be reviewed together, with the EDRs for the gas enclosure and
windows coming earlier. The designs of the installation equipment (WP1.3.6) for the photon detector
boxes, mirrors and gas enclosure are proceeding in parallel with the design of the individual
components.
There continues to be steady progress on the mirror procurement (WP1.3.5). There are ongoing
discussions with the CMA company (Tucson, Arizona) on the procurement and mounting of the 3.65 m
radius of curvature spherical carbon fibre mirrors, fitting within the constraints of the gas enclosure. We
are confident of achieving good spherical-mirror performance, and anticipate that the mirrors cost will
come within TDR expectations, albeit with £150k as yet unfunded (as part of the desirable additions
request to STFC). We have ordered a carbon-fibre flat mirror prototype from CMA and this has been
tested for reflectivity and divergence of spot size (D0). A test facility was prepared in CERN by Bristol
physicists, and this has operated well. Unfortunately this showed that the reflectivity of the prototype flat
mirror fell short of the 90% specification, the D0 was just within specification but marginal, as well as
there being a likely cost issue. Hence we have switched our focus to glass mirrors, for which several
companies have been approached and a prototype will soon be ordered. We are now confident that the
total flat-mirror cost will be held approximately within budget. The mounting mechanism for the flat
mirrors is currently being designed. The EDRs for the mirrors and mounts will also be prepared for
review by the revised July 2016 milestone. Konstantinos Petridis (Bristol) has taken over from Jonas
Rademacker as WP1.3.5 project manager.
WP1.4 RICH Electronics Readout, Data Acquisition and Controls
The design of the front-end digital board, which serves 4 ECs, is progressing well (WP1.4.2). The digital
Page 5 of 13
OFFICIAL SENSITIVE
LHCb Upgrade OsC PAR 1(14)
board design consists of a motherboard containing 3 Kintex-7 FPGAs. The layout of the prototype
board, which has the required geometrical footprint for the RICHes, is in progress. The fully populated
boards will be available for testing in around 6 months. There are two plug-in boards which sit on the
motherboard: the dbVTTX prototype PCB plug-in boards have been delivered, and the layout of the
dbVTRX plug-in board is in progress. The testing under irradiation of the FPGA that forms the core of
the module is in progress; it is not yet clear whether fuse-link FPGAs will be necessary. The digital
board EDR has been delayed by 3 months to June 2016 to accommodate the prototyping and radiation
studies.
Development of the digital board firmware (WP1.4.3) with design mitigation for single event upset (SEU)
is underway and proceeding in parallel with the irradiation programme. The specification for basic
functional readout for system integration is being developed and will continue into 2016. For the offdetector (PCIe40) firmware (WP1.4.4), the basic firmware for short term testing is being developed,
including the data compression algorithms with the potential to reduce the number of required PCIe40s.
The definition of the specification of the control software (WP1.4.5) is in progress (e.g. the configuration
of the CLARO frontend chip, the readout control etc). Prototyping of the basic functionality will start early
next year. In planning for the system test with pre-production electronics (WP1.4.6), the infrastructure
at CERN will be commissioned during the third quarter of 2016. A PCIe40 is required for readout and
although this has been ordered, it is unlikely to be available before the end of Q2 2016. Components will
be replaced with prototype and pre-production prototypes of the final modules as they become
available. We will also use the prototype firmware from WP 1.4.3 and 1.4.4.
WP2 VELO
WP2.1 VELO Software and Firmware
Work on WP2.1.1, 2.1.3, 2.1.4 and 2.1.6 is progressing according to schedule with milestone M2.1.3A,
having been met. WP2.1.2 has been removed as a result of the CG outcome (see above).
The adoption of the GWT serialiser by the VELOPix chip, rather than GBT as used by other detectors,
has meant that significant components of the common firmware of the experiment are not applicable in
the VELO. Additional institutional effort (no cost to this project) was added to ensure this work remains
on schedule. An FPGA workshop was held in Manchester in November 2015 and milestone M2.1.5.A
met. The project is preceding well and it has been demonstrated in simulation that the prototype
algorithms fit inside the available resources of the final FPGA, and the current prototype board has been
extensively tested.
2.2 VELO Electronics, Data Links, Off Detector Electronics
A detailed external review of the front-end electronics was conducted 17-18th November 2015. The
review covered all parts of the electronics chain the UK is involved with. This includes: the hybrids that
hold the pixel/sensor tile and allow the VELOPIX ASIC to be read out; the tapes that contain the data
links and the LV and HV cabling through the vacuum; the electrical properties of the feedthroughs that
allow the data to pass through the vacuum; the opto and power boards (OPB) that sit directly outside
the VELO tank and performs opto-electrical conversion, LV distribution and control.
Recent results have shown that there are some radiation hardness issues with the GBT chipset leading
to an increase in current consumption at intermediate doses. This is believed to still fit within the cooling
and power budget of the current design. The same issue may apply to a lesser extent to the VeloPix
ASIC where a significant increase in current consumption would cause a problem. Studies have started
to evaluate the detailed implications, hopefully it can still be accommodated by the present system but
we have raised this issue as an additional item in the risk register.
Hybrids
Over the past year (2015) hybrids have been produced employing multilayer Kapton PCB technology to
enable readout of ASICs. The hybrid EDR occurred in November 2015 completing an LHCC Milestone.
Page 6 of 13
OFFICIAL SENSITIVE
LHCb Upgrade OsC PAR 1(14)
Half-sized electrical and full sized mechanical prototypes are now at an advanced stage of design. The
hybrid design satisfies the required low mass and high frequency, radiation tolerance and wide
temperature service requirements. Delivery of these hybrids is expected in Jan 2016. The electrical
prototype are compatible with the prototype OPBs and will be evaluated together with those.
High Speed Links & Feedthroughs
Each VELO module will be readout out via 20 data links designed to operate at 5.12 Gbit/s and two
control links (ECS/TFC) at 4.8Gb/s. Three variants (different pitch/spacing) were produced as “tapes”
approximately 56cm long offering approx. 100 ohm differential impedance. Effort was invested in
designing PCB’s that could act as electrical prototypes of the vacuum feed throughs. Even though the
feedthroughs are no longer UK deliverables it was necessary to make electrical prototypes to evaluate
the concept and to test the hybrids and OPBs. Simulation and measurement of the high-speed data
tapes have been made. Currently effort is being invested in bringing the modelling and measurements
into closer agreement before making the first prototypes in industry.
Optical and Power Boards (OPB)
The boards are located immediately outside the vacuum tank and provide electrical to optical
conversion of data and control signals and provide the supply voltages. The board is based around the
CERN developed radiation tolerant components from the versatile link and GBT family. A prototype
design has been made supporting readout of a half-sized hybrid and will be produced in January 2015.
These boards will together with the prototype hybrid and data tapes allow for the evaluation of the
electrical design of the system once the VeloPix ASICs become available in April 2015.
2.3 Pixel Module
Sensors have been designed, and sourced from Micron in the UK and HPK Japan and tested in
testbeam. The sensor EDR occurred in June 2015 meeting milestone M2.3.1A and the corresponding
LHCC milestone. The Micron sensors n-in-n design had a feature that gives slightly high current at
edges. The use of n-in-n avoids the need for parylene coating which HPK cannot provide.
Design is almost complete for a next generation of sensors which correct this feature and have minor
geometrical improvements. Reception of detectors from Micron is expected late April 2016. UBM has
been provided at ADVACAM, IZM and “bumping” was performed at IZM. IZM is the only company that
claims to be able to handle the “thin-on-thin” bump bonding of thinned ASICS to thinned sensors and
thus we expect IZM to be awarded the final production contract.
Assembly
Liverpool completed the manufacture of the module testing vacuum chamber, completing milestone
M2.4.5A, and this has been commissioned in Manchester (assembly site) to the required pressure. The
CO2 “blow” system has also been commissioned with a silicon-pyrex micro-channel plate.
A new wire-bonder has been commissioned and test samples produced. A glue robot and pull tester
were purchased. The silicon clean room space has been divided to allow R&D for other projects
(notably ATLAS) to continue without impacting on the module assembly.
A baseline module design was fixed meeting milestone M2.3.4A and will be reviewed in 2016. Risks
remain on the thermal distortions of the module support structure. This stabilizing of design parameters
has allowed the critical high precision double sided assembly jigs to be designed for the attachment of
the sensors on micro-channel plate. These have been manufactured and preliminary tests show a
placement precision of 5 microns can be achieved.
Cooling
The provision of the micro-channel substrate remains one of the largest UK contributions to the project.
The EDR was held Nov 25th 2015 meeting an LHCC milestone. The dimensions and routing of the
micro-channels has been finalised and substantial prototype work done on, metallization, connectors
and pressure testing. Remaining issues that must be addressed before production readiness is
achieved include: decision on substrate thickness, handling, wafer dicing techniques, the final technique
used for soldering of the connectors. Although this technology is maturing rapidly substantial QA and
pre-production testing will be required to ensure that the risks associated with the substrates are
Page 7 of 13
OFFICIAL SENSITIVE
LHCb Upgrade OsC PAR 1(14)
minimized. Costs are on the edge and additional institutional staff resources are being supplied, a
modest overspend is projected in this area in the finance tables and will be evaluated at the time of the
PRR. Should additional redesign, and prototypes be required to address risks it is likely this will exceed
the existing cost envelope. Good progress is being made on thermal modeling.
2.4 VELO Mechanics and Integration
Detector-Half Bases
Oxford is undertaking the design and manufacture of the detector-half bases. Manufacture will begin
once the module and cable routing are finalised. Substantial work remains to be performed to finalize
the Hood and Tertiary vacuum design. These influence a number of key decisions such as the detectorhalf, cable clamps and routing. UK effort for the upgrade mechanics is allocated at a 0.2FTE/year. This
is proving to be insufficient to provide the required level of design oversight. We aim to increase the
Liverpool and Oxford based effort to around 1.0 FTE (from institutional effort) for 2016 which will provide
centralised system engineering and deliver a detailed programme for the final assembly and testing.
An important issue that influences the whole project is the question of whether connectors will be
permitted in the secondary (module) volume for the CO2 cooling. Connectors were not permitted for the
first VELO and all connections were orbitally welded prior to module mounting. Due to the design of the
modules this is no longer an option and either modules will require welding after being mounted OR the
use of connectors. A programme of testing the suitability of connectors has been launched in the UK as
no other partner has been found to take on this critical sub-programme. Non-approval of a
connectorized design by the LHC vacuum group represents a risk to the project and has been added to
the risk register.
WP3 (Computing)
The funding for WP3.2 only starts in 2017. Therefore there is no progress or change to report under this
heading. LHCb held a software workshop in November 2015 specifically aimed at addressing upgrade
computing. This will lead to a roadmap document early in 2016.
4. Outreach
The LHCb discovery of pentaquarks was the largest CERN physics news story of the year, and named
by the IOP as one of the physics breakthroughs of the year.
We have applied for and been awarded a place at the 2016 Royal Society Summer Exhibition on the
theme of "Antimatter matters", which will showcase the LHCb upgrade and the physics we hope to
discover. This was the primary objective of our pathways to impact outreach section for this grant.
5. Industrial Liaison outwith UK workpackages
While much of the general infrastructure for the upgrade proceeds via framework contracts, there will be
opportunities in the upgrade of the PC farm and its infrastructure, as well as the general infrastructure
as noted in the letter from the LHCb Upgrade Detector Coordinator of 30/4/2015. The timescale for the
associated market surveys and invitations to tender will become clearer towards the end of 2016.
The initial prototyping during the R&D phase of common hardware for the online system (PCIe optical
readout boards) was carried out in the UK by Exception PCB. A market survey for the procurement of
325 such boards (MS-4080/PH/LHCB) with a value of more than CHF750k, was launched in June 2015
and will close in the coming weeks. UK companies have participated in the market survey, but details
are not available until this closes.

Risk Register
Project Issues/Active Risks
No.
Issues/Risks identified
2.3.4
Microchannel plate layer
does not achieve desired
cooling, or is not vacuum
qualified, or requires
additional design effort.
3.2.5
UK share of Core
computing not covered
by UK
Proposed/planned mitigation
Engage with CERN experts and LHC
vacuum group. Secondary solutions based
on diamond (for example).
Core computing must be covered by
other countries delay to other areas,
reduced performance at Run-II start
Risk Status
EDR successfully
met. Safety system
being designed.
Need to continue
close monitoring.
Cuts made in 2015
CG outcome
increase risk of
loss of physics
output
The full risk register has been provided with updates. High risk items (prior to mitigation) are given here.
