This morning we went into the PSL to make some adjustments. The reference cavity transmission was down by quite a lot (~1.5V to ~0.4V) which normally would
have prompted an alignment session and we also noticed that the PMC POWERREFL was about 20% of the POWERTRAN rather than the desired10% or less. The following adjustments were made:
1. the PMC was aligned by adjusting the light into the PMC using M6 & M7 mirrors. Vertical adjustments only were made bringing the POWERREFL from ~3.1w to ~1.9w
2. The power level of the 80MHz RF level to AOM02 in the FSS loop was adjusted.
3.Power measurements were taken at different points in the FSS chain
4. PSL FSS TPD DC output at 1.602V
5. The FE watchdog was reset
