  • Laser was clipping on a laminated paper on the optical table. this caused signal on QPD2 and QPD4 be almost 0. Restarted the measurement after the issue was resolved

I realigned the entire CR1-4 setup

  • ensured that beam out of the chamber are at 6" height everywhere. Moved some iris to center them
  • ensured that the beam hits the 45 degrees in-vacuum mirrors at a height of 3.78" = 96 mm
  • checked that all incoming beams are roughly centered on the 45 degrees in-vacuum mirrors. Move some of them in-vacuum mirror posts
  • realigned the input steering mirros horizontally and the in-vacuum mirros so that the beams reflected from a water-level are not clippe anywhere
  • realigned the horizontal reference to the center of all QPDs

There was an issue with CR3 (clipping on the in-vacuum 45 degrees mirror). Realigned CR3 last in-air steering mirror and in-vacuum 45 degrees mirror.
