Current Status

• Low current beam overnight with some power supply issues (see below).
• Beam was bad most of the morning/afternoon.
• Will continue running J/Psi on kinematic Phase-3.

Current Run Plan

• J/Psi Experiment:
• Run Production Phase-2. Shooting for a total of 6.5 C for phase-2 kinematic before returning to Phase-3.

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

Current Issues

• Rotation controller needs rebooted. Will require access.
• HMS Q3 current readback errors. Alarm silenced. Will require hall access to power cycle.
• SHMS Dipole tripped early in owl shift. Remote PLC reboot fixed it.
• HMS side camera not functional. Will need to power cycle.

From yesterday: From Steve's logbook entry:

• 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.

• Concerning target alarms (loss of cooling power/over head) continued when running with hall A.

Special Requests

• Latif's GEM testing completed this morning during beam studies.
