SLinac/FEL SC1R Pumpdown is complete. Liquid levels will be updated shortly, and cryomodules will be filled shortly after that.

Tuners 3 & 4 were tested with both parallel (presently in place) and series motor winding configurations in place in the CMTF and passed range and hysteresis tests in the nominal series configuration. Once data collection on the parallel motor configuration performance is completed, we will revert to series wiring there.

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.
