Just a quick report now that we are back to NLN!
- After getting through various alignment details at 2W, getting to NLN is very smooth and requires no intervention
- The problem with the PI guardian last night was because I manualed over the "inject squeezing" state which also engages the PI guardian. PI damping engaged properly today!
- Naoki is working on SQZ alignment, reverting the ZMs to the July alignment
- Some visible excess noise in DARM below 60 Hz. A quick coherence measurement shows that a portion of this noise at least is LSC. We can retune the FF soon
- I ran a quick broadband PCal measurement that shows our calibration is off, unsurprisingly. Louis can help us recover the calibration over the next few days.
- We have still not set the y-arm green references, due to issues getting the ALS Y locked properly when in fully alignment. We can fix this on the next relocking
- We still have not solved the ALS Y WFS problem, and we still don't know what's wrong. However, we have improved the counts on ALS Y WFS B, which might help DOF2 run better when the loops are engaged.
- The current (not-well-calibrated and unsqueezed) range is reading at 123 Mpc
