Current Status

  • Continued running J/Psi on kinematic setting 3 high-t
  • SHMS HB problems right after last meeting. Called Steve. Jack came to help remote reboot of the PLC. This seemed to fix things.
  • Strange target alarms. Loss of cooling power?
  • Running at 55 -60 uA. Will ask for more if beam is stable.
  • Replace camera 3 (temporarily). Needs better cable placement.
  • Might turn off camera rotation. Need to follow up with Steve.

Current Run Plan

Notices in Effect for Shift Crew

  • Shift Leader is responsible for 50k replays. Even if the TO is actually doing them.
  • Target Operators: When the alarm handler goes white, it is disconnected from the IOC. Log it and include carlin@jlab.org every time. Acknowledge the warning. If it is still white and not coming back, restart the alarm handler. Do not permanently silence the alarm handler.
  • Missing Reference Times during the replay: check in the 50k. Check in full replay, if able. If it happens, call RC. Guidance to solve it is here: https://logbooks.jlab.org/entry/3654584
  • Target camera is inoperable at the moment.

Current Issues

  • Need to notify Steve to turn on rotation controller before rotation.
