-- Funding of experiment 

cost saving hunt

items

A. fridge at RAL: savings from 
1.  running the PSI solenoid with two phase helium instead of supercrit. 
2.  reducing VPLC channel count by 7 or infty
3.  issue of common funds: need to reach a reasonable proposal to the collaboration. 

B.power sources: it is urgent to have a good plan and to estimate how much funding (beyond already requested) is needed. 


--> integration

1. good progress from the AFCSWG 
proposed a scheme with absorber removable from the end. 
Notes: 
original scheme of Study II. 
flexibility for later absorber choices  
construct coil in one unit at one place. 
No objections were raised. 
Action: Endorse 

remaining choices concern mainly absorber itself. 
internal safety review end of 2003. 
==> action P. Drumm and A.B to nominate safety committee after discussions in Mice SG and interested parties. 

2. It was requested that more integration tasks are soon necessary -- cavity + coupling coil assembly
-- focus pair + detector solenoid and detectors.
     (shield -- HV protection etc..) 

when will it be appropriate to start on this?

--> Detectors
1. downstream PID. 
Grichine observed inadequacy of present layount for muons of 200 MeV/c and below. 
Action: study problem for well defined momenta (Grichine, Tortora)
  needed: angular + space distribution of muons from MICE 
Action: Yagmur and software group to generate samples of muons at differenct momenta (large emittance) 
 
More work needed on Cherenkov to adapt it to new momentum conditions, and possibly reduce size.
Action Gregoire/summers and Cernekov group

2. tracker choice

A. sci-fi.  Proceeding to build a full station with part of readout. (very nice) 
Multiplexing needs to be done at level of detector itself. Question of upgradability.
problem raised of effect of photons bouncing on structures or extracting electrons from them and generating noise signals. (needs to be evaluated by MC)

Fairly complete on software side (missing: Mux+noise+x-rays) 

B TPG. Going ahead with full size readout detector and HARP test. Small chamber worked already.

RF pickup and effect of x-rays is a concern to be addressed by the group. 
will have a go at a commando operation at lab G. Other methods may be of interest (RF antenna, tagged sources.)

C. choice criteria.
complete list was drafted by Summers and Gregoire (thanks!) 
groups -- and others! -- should go through it list and agree before (1 july?). 
Upgradability and manpower needed for operation and maintenance should be considered.


3. TOF: no more than one particle (of any type!) every 20 ns / counter.
safety margin of at least a factor sqrt(10-3) needed 1 hit / 600 ns about.  


-- > beam line
need more calculations to assert need for hardware and possible solutions around it. 
Action Drumm, Palmer, Roberts

At the same time hunt for hardware to be borrowed around the world (several appropriate quads or two coils) would not hurt. 

Action: reward for finding appropriate hardware. 

It was stressed that for momenta up to 240 MeV/c 10m of flight is an overkill. 
(was calculated at 300 MeV/c.)

--> RF background
MICE would like to understand how much reduction on x-ray/electron emission can reasonably be hoped with e.g. coatings. Request to Norem et al to integrate such plans in work programme at Fermilab.
