Commissioning goals
*track AAA: PSL
- fix FSS re-locking problem
*track A: missing RG gain:
- PR2 spot position during alignment
- Add digital camera of BS
- arm optics camera defocus & power monitor
- *** fix the 2x omega diodes for SB recycling gain readout
- check broadband mod of 2w PDs (POB and AS)
- new lens in front of POB_B
*track B: noise commissioning?
- shot noise scaling?
- check calibration
- try for 50W stable. Serious trouble with PI?
- pick operating point, then now-noise commissioning
- reduce RF45
- Aux length show exess noise - fix it!
Relevant to noise hunting: all test mass PUM coil drivers should be put in a lower noise state than state 2 (which is the noisiest state). State 4 is the lowest noise, but state 1 should be adequate as well. See 28264.
