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

• No new issues since yesterday.

Recently resolved Issues:

• Beam Right "Waterfall" camera works again after Dave Gaskell upgraded the firmware.

Unresolved Issues:

• Rotation controller needs rebooted. Will require access.
• HMS Q3 current readback errors. Alarm silenced. Will require hall access to power cycle.
• HMS Q1 and Q3 PSU M-panel (local front panels) are showing signs of failure. No action taken. Might be fixed with Q3 current readback error above.
• Ethan installed a current limitation board on the HMS Q2 spare PSU. Currently it is set to ~700A. Needs to be increased for CSV.

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.
