CCUM 7 9 11 1 3 5 2 4 6 8 10 12 The Tracker Outer Barrel system test The “rod” is the self-contained TOB building block 6 (SS) or 12 (DS) Si modules Interconnection electronics Control electronics Optoelectronics Cooling pipe + module cooling elements integrated on a CF frame • SS rod prototype tested and validated in 2nd half of 2002 • DS rod “final” prototype tested and validated in 1st half of 2003 Validation of the electronics architecture (functionalities of the CTRL chain) Test of grounding scheme and shielding of signals (study of noise) Performance with physics signals (b source, cosmic muons) Cooling efficiency (temperature map in data taking)
The rod test set-up at CERN Alu box, gas tight, with patch panel for pipes (C6F14 cooling and dry air) and other services (it can house 2 rods) Modules, optohybrids, CCUM, high voltage Daq PC with 1 TSC, 1 FEC and 3 FED cards, DAQ Software
