HAM 1 RFPD Checkout
Sheila, Stefan, Rich

Things went so well yesterday that it was a bit suspicious.

Present status:
1.  Finished a crude checkout of the tip/tilts after installing jumpers inside the coil driver chassis to enable the normal signal path.  The HAM1 tip/tilts are showing signs of damping, so the electronics are fine.  The anti-dewhitening is probably not right, so the servo needs attention.  (The HAM6 tip/tilt coil drivers have not yet had the jumper installed, so they won't work yet).
2.  REFL A and B Wavefront Sensors seem to be fully functional as checked out from the rack.
3.  Both the REFL and POP LSC detectors are in HAM1 and are functioning, but after much troubleshooting we found that there was a voltage missing in the DC wiring serving one of the LSC detectors probably inside the chamber.  This is despite testing each and every wire prior to installation beginning.  After finding that (and being so relieved that the detectors were OK) we realized that it's going to involve getting inside the chamber, which we will do in the morning.

Next Actions:
1.  Fix DC cable serving LSC detectors
2.  Do optical alignment of RFPDs
3.  RF AM measurements
