We had plan to continue 200 kV soaking of the gun this afternoon preferably with GaAs based puck. But seems like the puck swapping is not completed yet. Currently, the gun HVPS circuit breaker 13,15,17 Panel IB-PP3 is LOTO-ed. Therefore, HV conditioning is postponed until the puck related task/decision is completed/made. Wait for feedback from Joe Grames.

This morning...

1. Marcy and I returned three physics quality SSL pucks from Suitcase to Prep and moved three non-physics quality SSL pucks from SM to Suitcase, went very well.

2. Next we retracted the Mirror Puck from the HV chamber. The Long Manipulator movement is not smooth, bearings and/or configuration are suspects. We need more time this afternoon to investigate, I asked the crew chief to allow for this after the 1:30 scheduling meeting.

3. Shukui continued with Hall A laser HCO

Really nice work to all team members.

Chopper 1Y is functioning fine, and RF hot checkout up to 1D in the injector was completed yesterday morning.

This appears to be a readback issue only.

The local oscillator power for Chopper 1Y (R012LOPW) appears to be low (1Y is about 0.023 mW while 1X, 2X, 2Y are all about 10-11 mW).

This issue alone is not substantial enough to pull the chassis, so LLRF will address this when something else motivates more thorough or involved injector work. It appears that this readback failed around May 2025.

A viewer application has been created to make it easier to access historic entries from the 6GeV era preserved in the old logbooks database. It contains log entries recorded between 2001 and 2013. When the current logbook was initially stood up in 2013, the most recent 5 years of data was imported, so data from 2008 - 2013 overlaps and is available from the current logbook application as well as this historic data viewer.
