Last week, Riad and I found that the long manipulator that moves photocathodes from the prep chamber where they are heated and activated to the high voltage chamber was not working well.

Today, Joe and I had the chance to investigate more. The magnetically coupled manipulator has bearings in the vacuum which seem to be catching, and no longer able to move reliably and smoothly.

Following the manual, we adjusted the teflon sliders, which are outside the vacuum, reseated the external magnetic coupling and tried actuating it again.

1L09-The SRF vacuum group closed valve on VIP1L09B and turned on the ion pumps on VIP1L09B and VIP1L10A. The plasma pump cart was replaced and started pumping through the vacuum manifold. Checked for gross leaks.
Tomorrow, we will go through the vacuum verification list. If everything is good, we can proceed with processing.

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
