MICE-UK: progress report Progress:

WP1: B&I: Target u/g (Sheffield) … PD Focus coil assembly Spectrometer Software

Issues: Scientific approval Formal connections with iMICE Continuity of funding Scenarios for UK funding for MICE

WP2: Focus coil assembly - Oxford/RALNew design of magnet and absorber

Absorber now slides inside magnetIntegration much easierMore modular for hydrogen safetySimplified magnet designReduces costs

Quench analysis complete

Magnet specifications written, guide prices from companies and Oxford University.

Ongoing analysis of forces

Preparing for iMICE safety review (Dec03)

Current designsimplified integration

WP2: Focus coil assembly

Magnetic Analyses

OPERA calculations

Forces, torques and stresses on coils

Quench analysis

Currents, forces and heating

WP2: Focus coil assembly

Mechanical Analysis

~ 200 tons internal force between coils ~ 80 tons external 2D & 3D FEA analyses of coil support tube

WP2: Focus coil assembly

Simulations

ICOOL simulation of muons in MICE lattice

Specify construction tolerances & magnetic field errors

Perfect

5o tilt

WP3: Spectrometer instrumentn

- Brunel, Edinburgh, Imperial, LiverpoolPrototype:

All three stations shipped to FNAL

WP3: Spectrometer instrumentn

- KEK, OsakaLightguides:

All lightguides shipped to FNAL

WP3: Spectrometer instrumentn

- FNALD0 test stand:

Trigger etc. ready, assembly in progress

RF test done: effect << 1 pe (i.e. OK for MICE)

WP3: Spectrometer instrumentn

Preparations for technology choice 30Oct-02Nov: Have proved construction/collaboration Jp/UK/US Setting up to measure light yield, cross talk etc. RF measurement performed Tight but possible!

Updated costing: Mechanical: revised costing ~prepared. Shows saving

and is based on experience with prototype A. Bross (FNAL) updating electronics costing:

‘Borrow’ D0 spares? Implies negotiation with D0 … Build new VLPC cassettes … cost being evaluated

Schedule: Mechanical: revised following experience with prototype Electronics: being revised by A. Bross (D0 experience)

WP4: MICE software

Present focus: simulation/reconstruction adequate for comparison of SciFi and TPG Gridification: Done: Rapid generation of large data sets RF background generator: under test SciFi simulation: updated: under test SciFi reconstruction: updated: under test

Schedule to provide results for collaboration meeting is tight … but probably will be met

- Brunel, Edinburgh, Imperial

Issues Scientific approval

Discussions with Dan Kaplan and Alain Blondel: Need clear statement such as:

… The MICE project has been fully peer reviewed at both national and international level. The science case has been strongly endorsed in each peer-review process. CCLRC therefore approves the project subject to a satisfactory outcome of the Gateway process. …

Issues: Formal connections with iMICE:

Collaboration meeting: Initiate dialogue CCLRC/iMICE at collaboration board Informal dialogue UK funding agency/iMICE at

collaboration dinner … precursor to more formal meeting?

Project Management Board (chair KJP) Has not yet met … Membership is UK leadership plus iMICE

spokesperson(s) Important to hold first meeting to tie iMICE into

development of financial, managerial and operational cases/activities

Issues: Continuity of funding:

Seed-corn funding provided by CCLRC/PPARC following PPRP review have allowed significant progress to be made on all fronts

Essential to ensure continuity 2003/04 2004/05 2006/07 2008/09 … i.e. beyond the SR2002 period
