- commission input PZT alignment servo using OMC_T in a bright mich to reduce noise in 1-2KHz
- Along those lines, the REFL beam is clearly clipped in the alignment state which the alignment
- scripts leave us in. Investigate--the best way forward is probably to revisit the PSL periscope/mode cleaner alignment and the Faraday isolator.
- The Pentek at ETMY may be glitchy. The coil driver noise is higher there than any of the other
- test masses. It may be the coil driver itself, but suspicion falls on the Pentek.
