The PSL shutter was closed from the vacuum interlock trip. Today, I did the following:
- Re-aligned input beam to PMC to recover high transmission / low reflection.
- Re-set the LSC offsets.
- ETMX watchdog was tripped. Reset it.
- Opened the PSL shutter, IMC autolocker was able to lock the cavity almost immediately.
- Tested POX/POY locking, ran the ASS to maximize single arm transmission.
All looks good for now. I will probably get back to PRFPMI locking Monday. |
