Today so far:
- I moved SRM forward by 3mm
- Then I leveled the ITMY table
- At this point, bringing the ITMY oplev beam back onto its QPD got me back to green locking and IR flashes
- AS and POY beams are both making it out to their tables, as seen by IR card. (Though not to their in-air optics)
Here's my quick brain dump of things to do before we can pump down (anyone see anything missing?):
- Check the clearance of the POY beam at the SRM cage
- Re-do distance reconstruction measurements, confirm desired SRC length
- Lock the SRM cage down fully (right now, has 2 clamps on, and one laying unused)
- Align SRM for SRC flashes
- Adjust SRM OSEM positions as needed
- Adjust SRM oplev beam path, measure lever arm for calibration
- Confirm beam spots on output mirrors in ITMY and BS chambers are ok
- Take pictures of ITMY chamber.
- Closeup checklist
