Where are we now?
0. MICE RF AMPLIFIER 1 reached 2 MW!
1. Spectrometer solenoid SS2 is now ready for shipping.

2. SS1 see S. Virostek’s presentation coolling& training
3. Focus coil FC1 has reached full field in solenoid mode 
4. Present MOM is Chris Rogers, then Victoria, Ray, Victoria
5. EMR construction progressing well
6. EMR run will be in user run in october.
main objective: check device works and integrate in MICE DAQ/controls
+Scan momentum (mostly pion beams) to establish range/momentum relation
+ momentum distribution settings (muon beams) polarization (Rogers)

Important decision points
-- September 2013: installation of return yokes for step IV
Leaning towards return yoke (also smoothly prepares for step V/VI solution)
why not decide now?
--original motivation of baseline plan is to run step IV before Q3 2014-gone
-- it is not certain that the tracker readout can be properly shielded
(cryocooler, electronics) without return yoke + what else?
-- the cost and schedule implications of yoke implementation need to be
understood
internal MICE decision in early september and review in 2d half september
-- Around summer 2015 :
-- decision point for possible step V stop-over in 2017-2018
-- implementation of full return Yoke for step V/VI

Report from RSLR
See the slides by Robson that I sent. Here are ‘recommandations’ and ‘actions’
Automn 2013 is likely to be around November 13-15 2013
Outcomes from the RSLR Review –Recommendations (my explanatory comments)
Who is responsible for answering + who must be consulted
 Develop a risk-cost-benefit decision tree that shows how decisions regarding
performance/cost-schedule trade-offs might be taken, for the next round of
oversight meetings in the autumn 2013.
Garbincius & Preece + Grant/Long/Palmer/Bross/Gourlay
 Complete the financial analysis presented in the meeting of the savings of not
proceeding beyond Step V by the autumn. (NB. this question was asked as the meeting
with the reply that step VI is typically 20% of cost-to-completion in US, 30% in UK;
most risk is in the first RFCC, see comment later)
Garbincius & Preece + Grant/Bross
 Perform a cost-benefit analysis to support the final decisions on potential delays to
key staff appointments by the autumn.
Preece + Grant/Bross
 Establish a set of criteria for the demonstration of the successful conclusion of Step
IV for the autumn. (NB these are acceptance criteria of the constructed apparatus)
Blondel + Analysis group

 Update the project schedule to present the best, most probable and worstcase dates for Steps V and VI by autumn.
Preece & Krull + Grant/Bross/Garbincius
 Identify a set of appropriate intermediate milestones as a means of
monitoring and reporting progress by autumn.
Preece & Bross + Grant/Krull

Outcomes from the RSLR Review –Actions (these are essentially orders)
 Undertake an analysis of the cost of risk mitigation to the same level on both
sides [of the Atlantic, i.e. UK+US] to determine the potential impact on
schedule and cost-to-completion by the autumn round of meetings in 2013.
(NB at the moment there is no contingency included in the UK project)
Preece & Grant + Long
 Identify and recruit appropriate external specialists as members of the
review panel assessing the stray magnetic fields in the MICE Hall that will be
held at RAL in August/Sept 2013. Planning for the review should be starting
now (NB this was decided and started already by MICE but we are ordered to
do it)

Conclusions and recommandations of MPB (I)
OVERVIEW
Recommendation 1. Create a living, accessible and regularly updated one-page
"dashboard" summary of milestone achievements demonstrating the evolving status of
deliverables (eg magnets), initially focusing on Step IV, as soon as possible.
(would like a dynamic presentation of the data normally contained in Gail’s Milestone
table)
Preece & Rogers + Bross/Blondel/Hanson
Recommendation 2. Produce a one-page specification for the operation of the MICE
International Project Office and present at the next MPB meeting
(Andy Nichols has drafted some terms of reference – needs to figure out with all
parties how this can work)

Conclusions and recommandations of MPB (II)
SUPERCONDUCTING MAGNETS
Recommendation 3. Investigate the potential reasons for the slow and unusual
training of Spectrometer Solenoid 2 (and Focusing Coil 1). Check the protocols
(eg travelers) for the Spectrometer Solenoids and Focusing Coils, to establish
the level of quality assurance and to seek explanations for slow training.
Present results at the next MPB meeting.
(see next slide why this is relevant for MICE long term)
Gourlay & Bradshaw + Prestemon/Cobb/Watson
Recommendation 4. Re-evaluate the possibility of proximity shielding (partial
yoke) that takes into account the detailed situation of the present
infrastructure in the MICE hall and present a plan for future work at the
mitigation shielding review at RAL in August/September.
(NB this is one for Magnetic mitigation group. the committee felt that the
approach was perhaps too ‘manichean’ – a middle solution combining a lesser
yoke and some proximity shielding might be more optimal)
Tarrant & Witte + Nichols/Plate
RF SYSTEMS
Recommendation 5. Prepare a plan to test a prototype Low Level RF system
with the RF Coupling Coil at the Fermilab MTA, and present the plan at the
next MPB meeting.

A running schedule unknown:
+-225 A
FLIP
++114 A
SOLENOID
We plan to run both configurations
will the AFC magnet need re-training,
and how long should we allow for this?
MICE VC 11-07-2013 Alain Blondel
COMMISSIONING, CONTROLS & OPERATIONS
Recommendation 6. Present an integrated plan for all aspects of the control
system at the next MPB meeting. (for Controls team) Hanlet & Griffiths
Recommendation 7. Present the requirements and design of the MICE timing
system at the next MPB meeting, with particular emphasis on absolute calibration
by particle arrival phase measurement. Karadzhov & Ronald + Rogers
Recommendation 8. Explore the potential to achieve synergistic economies of
scale in the maintenance and operation of the liquid hydrogen system by working
with the ISIS moderator cryogenics team, and present at the next MPB meeting.
(that one is for Andy) Andy Nichols + Watson
Recommendation 9. Develop an on-site support plan for day-today operations,
maintenance and repair of the MICE hardware, and present at the next MPB
meeting. ( MICE operations group) Linda Coney + Preece/Bross
