A couple of the summing modules for PMTs 11-20 appear to have a lot of 60Hz noise on them. Have to swap them out next access...
Adjusted the cerenkov group discriminator threshold to 100mV to get it above some of the 60Hz ripple from the bad summing modules. Now that I think about it, that discriminator is remotely controllable so I just bumped the offset up by +50mV. Damn. I updated the offset in '/adaqfs/home/adaq/brad/camac_control/threshold' so the software reports the correct threshold...
Bumped the camera pointing to the BB Cerenkov gas panel so I had to ramp BB down, reset the camera, and ramp BB back up. (BB needs to be ramped down because the handheld TV used to view the camera while moving/focusing it gets creamed by the the BB field.)
Bob Michaels also did some work in the RHRS hut (a crate needed for his
parasitic test died).
