Block Schedule for June Upgrade Week (June 3, DESY)
Focus for the Week: interim point for simulation/studies towards Phase 2
– Report on detector/electronics longevity
– Report on results with initial set of questions/studies/modules, which we decide on
~now. Call this “Strawmen (1)”
– Define detector concepts, for high statistics simulation campaign. Call this
“Strawmen (2)” to report to collaboration prior to ECFA

Simulation studies
We need a campaign of simulation studies in 2013 to
– Present conceptual ideas and physics reach at ECFA workshop in September
– Present a cost scale to RRB in October
– Guide further studies and development of baseline detector concepts  lead into
decisions on Phase 2 scope by early 2014
First step in organizing: Simulation Workshop Jan 17-18

– Summary:
https://indico.cern.ch/getFile.py/access?resId=1&materialId=slides&confId=223203
Following the workshop there are two parallel email threads going on
– To define the studies needed and in which conditions they have to be performed
(what “enhanced performance modules”, used how and with which detectors ?)
– How do we do it – fastsim, fullsim, delphes… how do parametric extensions work in
the framework?
 Need a common forum for communication: Forward Detector WG. And three
meetings: cross-coord [Thursday’s meeting] - P2FDWG Simulation - Future Physics
 Goal to converge on a common plan to proceed by XC meeting Friday Feb 8
 Define timeline and resources needed identify possible contributors

From workshop: Main questions to answer and simulation studies
S1.1 Studies with Phase 1 detector
 Results by Upgrade week in DESY Jun. 3
S1.1 Which detector need replacement (full or partial) and after what luminosity ?
- Assumption for PU? 70 (Luminosity 2.4 E34 25ns)
- Assumption for aging (ECAL/HCAL/Tracker): 300 fb-1 (500 fb-1 as a second priority)
Can also be used to develop GED for phase 1
S1.2 What is the performance of the PHASE 1 detector at HL-LHC pile-up?
What is the benefit of increased rate at L1 and HLT output?
Pile-up effect in barrel Calorimeters - Requirements for new Tracker and Forward
detector - Trigger performance W/ L1-HLT high rates (without tracks or smeared tracks at
HLT?) - GED performance
- Assumption for PU? 140 (Luminosity 5 E34 with leveling)
- Assumption for aging? which detectors (EB/HB…), which integrated luminosity?
Full simulation with CMSSW_6_1_x
 Code integration Feb. 22:
- Follow-up in Offline meeting
- Need to develop simulation of vertex density (also needed for S2 and S3) Tracking
POG?: Assume luminous region with full crossing angle compensation (crab cavities)
and 5 E34 constant luminosity (β* leveling). TTI page (Anders):

From workshop: Main questions to answer and simulation studies
S2. Studies with Phase 1? detector plus “extended performance modules”
call it Strawmen (1)?  First results by Upgrade week in DESY Jun.3
What is the benefit for pile-up mitigation of tracking extension up to η = 4 and/or of
precision timing measurement over all η range?
- Beam conditions as for 1.2
- Main use cases
• Forward Tracking: Make reasonable assumption about number, placement and resolution of
•
forward disks (from TK layout simulations). With the POG/PAG define track parameters needed
Timing: Add a 10ps thin detector at the face of EE and EB
-
Other use cases (optimization of configurations)?
•
Endcap Calo
Assume HE rad damage is fixed and HE performs as Phase 1 detector
Assume EE is replaced, but for start use same tower geometry
Define smearing module (a) for EE rad damage (b) improved/degraded resolution in a new EE
•
Forward Calo
Assume HF is fixed and performance as for Phase 1 detector and/or define a smearing module to
simulate HF aging at high eta?
What can be done for a new EM+HAD HF to eta of 4?
• Tracker use tracks from standalone layout tool
• Muons 1.5<η<2.5 missing chambers, extension up to η = 3

S2. Studies with Phase 1? detector plus “extended performance modules”
call it Strawmen (1)?  First results by Upgrade week in DESY Jun.3
What is the benefit for pile-up mitigation of tracking extension up to η = 4 and/or of
precision timing measurement over all η range?
- Implementation of extended modules
• Original proposal at the workshop: Full simulation with CMSSW_6_1_x phase 1
plus extended modules, adding new object collections based on generated tracks
with smeared resolutions
 Discussion today on Tracking and Timing with new inputs from
Offline/Simulation and forward simulation groups
 Studies need forward tracking and timing in same simulation ?
From workshop: Main questions to answer and simulation studies
S3. Studies with complete simulation of Phase 2 detector
call it Strawmen (2)?  First results by ECFA workshop Sept. 2
What is the performance with the performance reach with proposed detector
concept?
What are the requirements for L1-Trigger tracks?
o Beam conditions as for 1.2 (PU 200 as a second priority)
o Tracker/Trigger
- First LB and BE CMSSW_6_1_x configurations, including first version of hit, stub
implementation in full simulation end of Feb.
- L1-Trigger track emulation to provide requirements
 FastSim/reconstruction geometry implementation to be investigated
 should provide RecHit for track reconstruction development
- Second version with code, digitizer improvements in June - could it be before (ECFA)?
- Phase 2 pixels and high η tracking timeline to be established
o Forward Calorimetry
- Strawman Forward Calorimeter is implemented in FastSim, based on EB geometry
(what about HE/HF?)  Higher granularity and timing implementation to be
investigated in conjunction with possibilities offered for S2
 Studies need Tracker/Trigger/Forward detectors in same simulation, fullsim or fastsim?

Next steps
o Today:
 Decide framework for S2 studies ?
o By XC next Friday:
 Answer questions in previous slides
 Establish schedule and resources needed
- identify contributions from groups/individuals
 Establish priorities
 Agree on organization of the work
