1. Detector Systems Update MICO April 14, 2008

2. MICE Detector Systems  CKOV u Nothing new  TOF0/1 u H6533MOD PMT assembly reliability is the main concern. u Hamamatsu has discovered that in the broken returned PMTs (8 out of ~65) the problem is connected with the active divider: a broken MOSFET + capacitor. u They are investigating, but no more news were given. u Of the new 8 PMTS delivered end of March: after one week of tests, two seem to have a broken divider and two have a random discharging behaviour. u The disassembled TOF0 is under test to avoid discharging PMTs and PMTs that may show problems in beam, by trying to substitute them and use pvc holders (instead of anticorrodal ones). u This has amounted to build/rebuild the detector twice. u No clear delivery schedule.  Calorimeter u No Update

3.  Tracker Electronics u Progress on Firmware u But multi-board readout, LED tests and full system test still need to be performed and evaluated before ship date can be determined
