12/3/12 Meeting Notes with Mac and George at ISU
Construction Proceedures:
Chambers outside cleanroom should have covers to keep dust off buss wires
Cap 113 (Brown one) needs to be replaced on STB board.
Need 2 amp fuse on 5 Volt supply to pre-amps.
Chamber grounding (ground through HV cable)
Chamber operating procedures
1.) post amplifier in VME crate had 150 mV peak-peak noise
2.) Stop using the current ADB crate
ISU Tasks:
1.) Install cover on top of chamber, top could be made from home insulation sheets that has been covered with paper or plastic sheeting.
JLab Tasks
1.) What are the fault conditions on the STB board when the power supply exceeds voltage/current
2.) Need signal cables with strain relief connects that have the shielding wrap grounded on the STB board but not grounded on the DAQ cabinet
