Current Status

Current Run Plan

  • Finished up kinematics 2, and started kinematics 4.
  • Will stay at setting 4 for the duration of the experiment.

Notices in Effect for Shift Crew

  • Shift Leader is responsible for 50k replays. Even if the TO is actually doing them.
  • 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

Current Issues

Recently resolved Issues:

  • Rotation controller was rebooted and Q3 current read-back reset during Steve Lassiter's access this morning. Rotation controllers are remotely disabled, and Steve should be contacted to re-enable them if we need to rotate (shouldn't need to).

Unresolved Issues:

Planned Accesses to the Hall

  • In order to rotate the spectrometers and change central momenta we will need access to the hall. Whether we need a longer access with survey/sweep or a short escorted access depends on if we want to do anything else while we are down. Changing the Cherenkov pressure is one task would could do with a longer access (~1 hour). Steve should be able to rotate and set magnet currents in a short access. This should be decided by the end of this meeting, so we can inform the relevant parties.

Planned Accelerator Configuration Changes
