For my note-taking:
- Lock PRMI with ITMs as the MICH actuator. Confirm that the MICH-->PRCL contribution cannot be nulled. ✅ [15960]
- Lock PRMI on REFL165 I/Q. Check if transition can be made smoothly to (and from?) REFL55 I/Q.
- Lock PRMI. Turn sensing lines on. Change alignment of PRM / BS and see if we can change the orthogonality of the sensing.
- Lock PRMI. Put a razor blade in front of an out-of-loop photodiode, e.g. REFL11 or REFL33. Try a few different masks (vertical half / horizontal half and L/R permutations) and see if the orthogonality (or lack thereof) is mask-dependent.
- Double check the resistance/inductance of the PRM OSEMs by measuring at 1X4 instead of flange. ✅ [15966]
- Check MC spot centering.
