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.


2.) Install 208 Volts for ADB crates that will be sent by JLab to replace the one they have given us.

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
