RM702 High Alarm

7 hours 45 minutes ago
Log Number: 4481921Logbook(s): Entry Makers: bschaumlBody: 

RM702 High alarm came in through the alarm handler. We contacted RAD Instrumentation Support on-call and they assured us this was an expected reading and this seems more like an issue with an alarm handler setpoint or something. They concurred that we can send back.

Hall C BLA Calibration Results

8 hours 3 minutes ago
Log Number: 4481915Logbook(s): Entry Makers: bschaumlBody: 

Applied two iterations of changes to the Hall C channel scaling, going from 0.7432 to 0.7119 to 0.7138. IBC3H00 now matches IBC0R08 much closer than before and we were able to get up to 46 uA before tripping on (Fig. 3)a dump diffuser raster 2 fault. The hall is only asking for 40 uA so I am fine with only calibrating this far.

One somewhat confounding thing is the "Commit Status" indicator didn't turn green on the last commit. I think it's alright as the new channel scaling got applied according to the screen and PVs.

Hall A nd C dump O2 concentration and higher current

8 hours 13 minutes ago
Log Number: 4481911Logbook(s): Entry Makers: jhowardBody: 

With Hall C requesting 40 uA, checked with the PD about any concerns with sending that high of a current while O2 concentrations are elevated. At the moment we are oked to send up to 50 uA if possible, but we will keep on eye on the concetration, and if it spikes, we will talk with the PD and Hall and figure out a way forward.
