1 MICE Report to the CMPB February 2008 Ken Long, Andy Nichols and Richard Apsimon 22nd Feb Project Manager’s Report 2.Project Status, risks and schedule 3.Financial status

2 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 de-scope option (magnetic shield wall procurement postponed to Phase II) 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 complexity and cost and to identify 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

3 MICE Target (in ISIS) Target & Controls. Pre-installation  Stepper motor & interlocks ok.  Target actuated 1000 times ok.  Good vacuum (3.3×10–7 mbar).  Absolute position w.r.t. beam pipe measured. Moved to ISIS and connected Sunday 20th  Several damaged fibres discovered. (Poor installation)  Optics (approximately) set up.  Stepper motor & interlocks checked.  Target raised & lowered several times.  Operation from MICE LCR difficult without network. Some work remaining for Installed Target  Adjustment of optical amplifiers, interlock programming, gate valve to be open, PPS ……….  Stepper motor control under investigation at DL and, of course, permission from ISIS to operate!

4 Secondary MICE Target Actuator & electronics (almost) completed & tested in Sheffield – 50,000 pulses. To RAL 13th February and re-assembled in R78.  Unusual pulse-to-pulse variation.  Failed after ~600 pulses.  One coil (of 24) found shorted to ground & burnt out. Internal ground not connected in Sheffield test!  Spare stator installed  New welded seals at Daresbury last week  Brought back to RAL immediately (untested.) All electronics now at RAL.  Problems still exist so has now be taken back to Sheffield for further investigation.  N.B. Stator currently in ISIS had done >2M pulses ok. Future – investigating better quality insulation (double layer?) with manufacturer. Need new QA procedures for coil insulation.

5 Phase I beamline in MICE Hall Shielding complete & D2 positioned Since then:-  D2 fully connected  PSI Decay solenoid installed With shielding Aligned  Q4,5 & 6 installed  All girder boxes built & installed  Power & interlocks connected  Water being finished  Alignment complete Still to do  Cherenkov mounted Stand required modification  ToF0 delayed. Due early March Install with Cherenkov  Q4-6 water and final tests  Q1 power supply due last week  PPS to be connected – this week Sept 2007 Feb 2008

6 Work in ISIS vault during Xmas shutdown

7 Status of tracker build: schedule Tracker schedule:  Tracker #1 complete in R8  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/de-install in Hall, run with beam?

8 Linde refrigeration Spec:- 4K (56W solenoid + 10W transfer )  In November we saw about 51W + 10W Managed to cool decay solenoid to ~20K –Ran out of time, not cooling Problem ‘traced’ to missing insulators  Jan 08, a reduction to 47W + 10W Problem now believed to be turbines –Evidence of carbon / graphite dust –Bearing failure? Turbines due back last week Engineer ready to re-fit & re-test  We trust that this the end of the problem.  Scaffolding built around decay solenoid  Gas rack and piping ready  Need access to DSA and permission to dismantle transfer line.  DeMaCo will return to re-install transfer line into DSA 17 th March.

9 Technical Co-ordination, Phase One The shared post of PM/TC has worked quite well Six months ago there was much for us to learn:  Revised the WBS  Now have a clearer picture of tasks and responsibilities  Led to better understanding of the project  Technical detail and information flow was not obvious  Engineering content of Infrastructure WP had been grossly underestimated  New Hall Manager, together with re-structured meetings, is a vital link in the project  Some very good progress has been made in the Hall build-up, but there have been a few technical problems… Clear that we have to plan better for Phase Two

10 Technical Co-ordination, Phase One Delay to target running:  Ideally, management of design and manufacture should have been in one place  Mechanical design of the bearings and shaft could have been improved to mitigate dust problems delays and QA problems  On & Offline targets should have had parallel working  One Project Engineer identified at Daresbury for target, effective, but rather too late to make big difference If there is a limited target programme in Phase Two:  Mechanical re-design, bearings, shaft (important)  Single engineering oversight  Should ISIS take responsibility for installation? Start up of Q4,5,6  Has been delayed as they are not connected to water  Result was we missed completing before ISIS started and lost access to DSA All services and ancillaries must be captured on installation drawings with parts lists –  simple stuff, but surprisingly difficult to implement

11 Technical Co-ordination The Infrastructure project:  Magnetic Shield walls  Rolling platforms  False floor  Concrete floor removal  Excavation of ISIS mound  DSA Roofing  Air Conditioning  Water  Electrical The engineering content was seriously under-estimated, what have we done?  We now understand it (Don’t like what we’ve found though!)  Broken it into more digestible chunks, i.e. North, South, etc  Appointed new WP1 Manager (Tim Hayler)  Limited de-scope possibility (rolling platforms)  Tenders, orders, etc underway, see Richard’s slides

12 Technical Co-ordination Infrastructure technical status:  Following big-ticket items are committed: South shield wall support structure Air conditioning units Concrete floor removal  Design work almost complete for: False floor North wall shield support structure DSA roofing and walkways  Four sensible offers received for ALL magnetic shield plates (£150k – £200k)  Remaining design work: MICE Hall roof layout (not yet started) & check the roof’s structural rating –Fence between MICE roof and Injection Hall Installation drawings for CDM records (hopefully a collating exercise)

13 Technical Co-ordination  We have been asked to provide these but have no funds to do so –Fence (or hand rails ) around the entire perimeter of the MICE roof –Permanent stairway giving access to roof So the Infrastructure will over-run Phase One….  Three main effects: Will delay Step II & III of MICE Stack-up of deadlines means Heavy civil work will be concurrent with tracker/solenoid integration – cannot be allowed Spending on infrastructure (manpower & capital) carried into Phase II  Open questions: We can stage the build of the magnetic wall, not a cost saving, in fact probable cost increase, but we can tailor to meet Phase II beamline build schedule better? –Direct cost saving from change of rolling platforms 2-6 for off-shelf slides Carry on as we are option: basically the infrastructure work dominates the Hall until mid July 2008

14 Technical Planning for Phase Two We have to plan better:  The Phase One Infrastructure Work Package should convert into Integration & Services for Phase II:  It’s very important that this is understood and properly resourced, because the risks are greater: More diversity in the beamline elements Safety, technical, financial and collaborative issues The Hall will be full of equipment – less space than we think  The current WP1 Manager can do it, but must be backed up by suitable, technical person  Better use to be made of the Technical Board Integration & compatibility issues will become more important Currently the Hall baseline layout is a huge 2D CAD drawing ‘owned’ by one person. We will fail if we carry on like this  The drawing is too large and crowded  It has no dimensions or datums for beamline items  No services detail shown  All technical integration decisions are on the critical path at the mercy of one overloaded person

15 Technical Planning for Phase Two We will convert it to 3D CAD assembly – partly done already:  Access by multiple controlled users possible  Engineering decisions can be made in parallel  CAD models more easily shared among collaborators  Dimensioned plans can be extracted A couple of worries:  The RF and LH2 projects both have the potential for large unforeseen expansions of engineering effort: The RF power distribution is currently ill-defined The LH2 is an R&D project at present and the lead engineer left last year (replacement identified – Mike Courthold)  Interaction with the rest of MICE for both these activities will not be straightforward  The Phase II effort profile estimate is taking shape, but it must allow sufficient margin for the above and identify the right person – discussions underway with EID  Integration & services must be identified as a discrete Work Package.

16 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/retirement 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) …

17 Phase I finances:

18 Phase I finances: infrastructure

19 Phase I finances: over-run:

20 Phase I: possible re-definition of scope Outturn forecast in excess of allocation +WM + contingency  Therefore seek a re-scope that will bring the total spend within 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: Simplify support Reduction in quantity of steel –Thickness –Perhaps north (linac side) wall need not be as thick »Extreme possibility: north wall is not needed (unlikely)

21 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 Staged build –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 likely to result in an overall increase in cost: –Though the spend profile may be more easily managed

22 Phase II finances: MICE-UK Phase II deliverables: STFC funding cuts likely to imply a significant reduction in resources …

23 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:

24 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/ months +14 months Urgent action is required!

25 Phase II finances: consequences: risk Risk: loss of post. doc. Staff:  Significant damage to expert UK team established in Phase I  Implies significant reduction in potential for UK impact in analysis/exploitation phase Tragic! Urgent action is required!

26 Reputation risk: STFC RAL is the host laboratory:  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
