Still scraping in AE

Only running nanoamp beam, so not much position information, but IIXAE02 and Hall B's current track almost 1:1. Will have to revisit at some point, but for the moment leaving good enough alone to prioritize beam uptime.

RM30 Locked Up and Alarming

1 day ago
Log Number: 4483756Logbook(s): Body: 

Found RM30 in alarm with both Gamma and Neutron readouts displaying maximum dose rates. I believe the unit and probes may have experienced too much exposure for too long. Replaced power supply card preemptively due to the fact that it had been in alarm for so long. After power cycle, the unit came back up with expected readings. No further work needed at this time.

RM30 readback error

1 day 2 hours ago
Log Number: 4483748Logbook(s): Entry Makers: shrinerBody: 

While trying to take Hall B to Controlled Access, the BSY would not go back to Beam Permit because of a radiation monitor. Apparently RM30 is receiving a dose of 9990000000 mR/h, and has been since ~1150. However, it was not noticed until now because the entire machine has been in Beam Permit since then. Contacting RadCon for further guidance.
