4 Principal milestones

5 Progress since Jun08 September 2007 June 2007 February 2008

6 Organisation

Project-management: Discussions started within collaboration to define MOM team: Plan to start Nov07 iMICE positions, Project Manager/Technical Coordinator and MICE Operations Managers must be agreed by MICE Collaboration Board ant CM19 (Oct07) New team:

8 Organisation Project management team established:  A.N. Other PPD: P. Flower, in place from October Took responsibility for testing completed Q35s and D2 (and other things!)  MOM team now in place: Past: Blondel, Long, Zisman Present: Gianninni (present MOM) Future: Apollonio, Kyberd, Ellis, Grauhlich, Long, Bross, Zisman, Kaplan, Blondel Project on much better footing, but:  PM (R.Apsimon) has applied for early retirement Consultation over successor has started  P.Flower has applied for early retirement  Other staff have applied for redundancy/retirment Uncertain times! WBS: change in infrastructue work package manager:  T.Hayler replaced C.Nelson from January 2008 Preparation of reports:  Much better, but still some work to do …  For Phase II plan to set up a data-base (in common with UKNF) …

9 Phase I finances:

10 Phase I finances:

11 Phase I: possible re-definition of scope Outturn forecast in excess of allocaiton +WM + contingency  Therefore seek a re-scope that will bring the total spend+requitement with the £9.72 envelope Option:  Move procurement/installation of magnetic shield walls out of Phase I  Undertake redesign with a view to simplification of design and reduction of cost as part of Phase II Technical details from Andy Nichols Magnetic shielding will be required in Phase II  Possibilities for cost reduction: Reduction in quantity of iron –Thickness –Perhaps north (linac side) wall need not be as thick »Extreme possibility: north wall is not needed (unlikely) If less weight of iron, then may be possible to simplify support –But, structure needs to support magnetic forces

12 Phase I: possible re-definition of scope Present schedule for build of magnetic shielding:  Start April; complete end of June  Heavy civil construction in conflict with running MICE with tracker: Concrete dust/metal swarf incompatible with tracker electronics Agreement with FNAL precludes heavy construction work in vicinity of VLPC cryostats (VLPC cassettes are D0 live spares)  Significant schedule issue Delay/redesign magnetic shielding: pros and cons:  Pros: Design for a cost saving: reduce capital cost and perhaps a staged build Staged build: –Would allow ‘just enough’ steel to be installed for each stage in MICE build up –May allow data-taking to be scheduled in between sections of build  Cons: Redesign implies delay to installation start and increase in staff effort required Staged build might result in an overall increase in cost: –Though the spend profile may be more easily managed

13 Tracker #1 complete in R8 Tracker #2:  All stations available and QAed  Waveguides in production Expect to polish at FNAL in March  All components for space frame available  Will complete fabrication of tracker #2 by end of March Location pieces for installation in solenoid all manufactured  Procedure defined, space-envelope discussion will be coordinated by PM Spare stations:  Bodies being machined, will complete and QA by end of March 2008 Status of tracker build: mechanical

14 Status of tracker build: station QA

15 Station QA summary:

16 Status of tracker build: slow controls

17 Production cryostats 1 and 2 ran smoothly at operating temperature  But, cassette in cryo #2 has developed an internal leak and will have to be pulled Cryo #3 is cooling down  Operating not yet satisfactory (6.2K at 60Hz?) Cryo #4 has its cassettes installed  Almost ready for cool down AFE power mods complete for Cryo #1,2,3  No longer have low voltage power problems Target is to ship system (Cryo #1 and Cryo #3) by end of February Status of tracker build: cryo system and VLPCs

18 VLPC system: photos:

19 Significant progress in D & A FPGA code:  Issues: Programmable look-up table code (S.Galagadera) support Debugging of AFPGA buffer –Ongoing Test of PLL on frequency-varying ISIS clock  Goal: complete by April Zero-suppression scheme implemented Fast-clear implemented Testing of VLSB has revealed some issues:  Set-up time unacceptably long, implementation of correction for this uncovered some ‘bugs’ Work is in hand to correct this Goal: send system back to RAL in March Status of tracker build: electronics and DAQ

20 Read-out and DAQ: timing signals: Timing r/o demonstrated:  Crucial for step V

21 Status of tracker build: schedule Tracker schedule:  Tracker #2 to be fabricated by end March ’08 (means assembled space frame in coffin)  Cosmic ray test of tracker #1 started before end March ’08  Continuing resolution of installation: Run with cosmics, install in solenoid, run with cosmics? Run with cosmics, install/deinstall in Hall, run with beam?

22 Phase II finances: MICE-UK Phase II deliverables:

23 Phase II finances: profile in line with PPRP recommendation As presented at September OsC: STFC funding cuts likely to imply a significant reduction in resources …

24 Phase II finances: guidelines from J.Womersley Seek to defend a continuing accelerator R&D programme at the level of ~£10M / year Guidelines for the MICE-UK and UKNF programmes:

25 Phase II finances: first attempt to satisfy guidelines:

26 Phase II finances: consequences: Significant (and unrecoverable) delay:  Above assumes contract for focus-coil modules is let on the 29Feb08 Implies first payment this financial year  To get close to requested profile, had to introduce arbitrary 3 month delay to start of manufacture of second set of coils Moves payments into financial year 2010/11 11 months 14 months Urgent action is required!

27 Risks: Scientific:  MICE results lose impact because results are not timely Damage to international partnership:  Integral of cost to international partners rises significantly STFC/RAL reputation:  Over the past year, the international collaboration (the US in particular) has increased its investment in MICE Phase II  For the UK to delay the schedule of the experiment risks not only the timely inward investment, but the UK reputation as a reliable collaborator and host

Personal comment: Everything to play for! Only ‘elephant in the room’ is the target dust issue Being addressed appropriately Much to do but: Likely to meet be ready for Christmas shutdown Likely to be able to carry out work required in Christmas shutdown Tracker likely to be available when required for Steps I and II Phase II: International and UK preparations well advanced Lack of UK resources beyond March 2008 may hold up project! Conclusions/issues September OsC

29 Conclusions and principal issues: Conclusions:  The increase in the pace of the MICE-UK project has now been maintained since June 2007 Technical progress from RA and AN …  The outturn forecast is in excess of the £9.72M envelope A possible re-scope option (magnetic shield wall redesign) has been identified Issues:  Phase I resources need to be carried over into financial year 2008/09  Since some magnetic shielding walls are required for Phase II, the best way forward needs to be identified: Noting that the infrastructure project now has gathered momentum, the project teams preference is: –To review rapidly the design with a view to reducing cost and identifying whether a staged build is possible; and –To push ahead as close to the present schedule as possible  It is urgent to resolve the funding of Phase II
