1. MICE PID & trigger Detectors MICE CM11, LBL Feb 12, 2005 for the PID team Bonesini, Cremaldi, Gregoire, Kahn, Roberts, Sandstrom, Summers, Tilley, Tonazzo, Tortora, Torun, Wilson and more

3. in the PID Summary Talk at CM10 in UK the basic conclusion was thatwe are advancing well enough on hardware design not fast enough towards a serious G4MICEre-evaluation of PIDperformances We have had since one short meeting Wed Nov 24 a useful meeting of general planning on Dec 21 a meeting of first results on Jan 26 a meeting with more results on Feb 2 a parallel session here at LBL Feb 11

4. In general, no major new progress from CM10 to CM11….. more like a few months of consolidation striving to complete another revision of our 8thPID Chapter of the TRD Striving to eliminate not negligible obsolete information & inconsistencies still remaining to make it the credible repository of PID detector data. Geometry files including PID , will be added by Yagmur in Ch. 3 (Simulation) incorporate realistic drawings of PID detectors in the general MICE layout general outside dimension of each device including external cases and supports.Wing Laa& al. tool up for final design downstream field maps files of downstream electron and muons (G4BEAM & G4MICE) and full re-evaluation of performance Implementation of TOF, CKOV I & II and MuCal in G4MICE feed PID detectors requirements to the resuming effort on DAQ & controls survey questionnaires filled for all detectors ! ! !

5. No change

6. Apertures No change. But now implemented throughout. http://people.na.infn.it/~palladin/MICEPID/TransversePIDLayout.pdf standard definition of the apertures of the PID devices based on G4BEAM studies Longitudinal coordinates being revised and text, tables, figures updated accordingly New numbe r s

7. Updated study on SEP04 watch out ….. we are already waiting for JUN05

21. A warning from Steve New plot from Don soon Adjust n?

22. Steve’s effort … in contact Lucien & Ghislain

23. Rikard

27. dubious … Rikard’s fresh look welcome

28. CKOV I ………….. Cremaldi & Summers reaparecidos

29. CKOV I light collection …. to be improved

30. CKOV I 3D

31. 12 * 4 cm both views

32. 8 * 6 cm both views

33. Measurement campaign in the spring R49998 TOF0 fine mesh R7761TOF I & II

42. PID @ CM11 : slowly lifting CM-10 bad marks TOF-0 … find a final site with moderate rates ……. < 3.8 MHz validate PMT choice (Ham 4498) Upstream done in progress CKOV-I… (almost) no news, evaluate performance dormant done TOF-I … find a final site, with moderate B-field, < K-gauss validate PMT choice (Ham 7791 fine mesh) in progress Refine evaluation of performance If modified layout and/or thickness, re-evaluate not necessary, so far done TOF-II…establish consensus on B-shielding and active area validate PMT choice (Ham 7791 fine mesh) Downstream in progress CKOV-II establish consensus on active area implement simulation in progress progress too slow MUCAL… establish consensus on active area debug simulation in progress progress too slow define size,evaluate performance in progress progress not fast enough Try to progress on digitization and controls resuming, new DAQ czar needed
