All conditions to begin LLRF testing -- valve interlocks bypassed, 2K cryo -- look to be converging such that can begin LLRF testing this afternoon. Friday will be a back-up date for LLRF. Then roll into SRF commissioning Saturday.

Discussed with task author. Yes, can be done in Controlled Access. Will aim to do this Mon 2/23 in the NL under Controlled Access. Back-up of Tuesday 2/24 in Restricted Access in the NL. Once the PTW is on-issue, this task is approved. Added to SAM Cal and Work Map for Monday 2/23.

Temporary configuration changes were made to the 2L25 Vacuum controls to allow for RF testing while warm region girders are installed:
-Simulator relays on VBV2L25A and 2L25B.
-Set Instrument Air Pressure interlock limit to 0 psi.
-Powered off controllers for VCG2L25A, VPG2L25A/B and VCG2L26A,VBG2L26A/B to satisfy Ion Pump A HV On permits.
-Powered on the IPPS for VIP2L25A and VIP2L26A with no loads connected.

With these changes made RF testing can begin swing today.

Body: 

Temporary configuration has been undone.
Valves, Ion pump and convectron has been plugged back in to running configuration.
All readbacks are good and valves cycle correctly.

Ready for continued RF testing.

Today Ali and I used 90 min of 1D beamtime to measure the analyzing power of the photocathode, this relates to the difference in quantum efficiency when the laser is linearly polarization (not circularly polarized). As a function of beam current we used the Hall A laser @ 249.5 MHz and sent beam to PCUP from 5 to 65 uA, then used the rotatable halfwaveplate to measure QE as a function of the orientation of the linear polarization.

To make the light linearly polarized at the photocathode we first turned off the RTP high voltage drivers, fig.
