Apologies from DF

2 Oct 2008 PC 3324

Some priorities

1) Effect of shield-induced error fields on performance of MICE

UB, CR & JC (with JHR) to look at this with both ICOOL & G4MICE

Not real show stopper (CR, last meeting) but

Details at 1% level need understanding

Needs ICOOL check (UB doing this)

Fine grid (error) fields available

Problem in “No-Shield Wall” map

Some problem with matching beta-functions to be resolved

2) Analysis of MICE beamline & beam, i.e. characterisation using what we have, esp. TOFs

Momentum measurement, emittance measurement & PID

Mark, Marco (& Chris) to work together to (at least) understand models of Qu’poles in G4MICE etc. and develop Mark’s emittance measurement with TOFs

Would like to introduce beam as a topic for these meetings (but not details like magnet PSUs!); possibly no other forum exists??

3) STEP I (tracker + NO solenoid) needs some study.

What can be learnt?

Optimum beam?

CM22 19 – 21 October @ RAL – Agenda Analysis sessions at CM22

Sun 19 Oct 13:30 -- 15:30 "Beamline & Step 1" May not happen, really beamline ?

Tue 21 Oct 11:00 -- 12:45 "Step 1 Results & Analysis"

Presumably Analysis in general; 105 minutes

AGENDA

Progress since CM21 in June:

MR - Emittance measurements with TOFs 10min + 5

DF - Spectrometer alignment & Statistics 10min + 5

TH - Spectrometer field mapping 10min + 5

New results/issues:

CR pp JC - Effect of shield walls on MICE fields - overview 5min + 5

CR - Effect of error fields on performance (G4MICE) 10min + 5

UB - Effect of error fields on performance (ICOOL) 10min + 5

CR - G4MICE -- ICOOL comparison 10min + 5

What have I forgotten??

Need volunteer to coordinate in my absence (& give a talk for me)

*Must make room for any beamline stuff if requested
