Starting off with Credited Controls. These are must-haves for any beam delivery to Hall D, be it CW, tune / pulsed, etc.

The latest status of Hall D Credited Controls can be found here: https://ace.jlab.org/jam/verifications/destination?destinationId=12

There are four credited controls currently red-X Not Verified. All are RadCon verifications:

Took measurements, replaced IPM5C11A's controller as it got stuck in a bootloop on power on. going to leave atlis and paperwork open such that we can work on it if the issue continues and an opportunity arises. So far we are not planning any further accesses into the north for today.

Body: 

DC power has completed hookups for the YBBS06 klixons, RTDs, magnet leads, and shunt leads. Klixon drop checks were performed, and all results were as expected and passed. ABIL tags were removed from the magnet interlock chassis. This concludes all DCP work downstairs for the YBBS06 magnet.

Updated Time Estimate. Task approved. Please check-in with Crew Chief before performing work. I'll relay to Ops the caution to expect the NL gangphase to be up to 180deg off when recovering beam later this week.

Today Jerome, Joe and I measured QE anisotropy of the photocathode using Hall A laser. The QE anisotropy was measured in the range of 5uA to 65uA in the steps of 15uA. The RTP was turned OFF for these anisotropy measurements. The RHWP angle set point was rotated from 500 to 7000 in steps of 250. These setpoints in RHWP rotation angle were so chosen to avoid the freezing (getting stuck) of RHWP near the end of set points ( 0 and 8000). The measurements were made for both IHWP IN and OUT configurations.
