Report of work

• Type A:
  • ETMX yaw position was adjusted and upper tower ETMX seems to be fine. Oplev is off from the center and it means that cryo payload may be touching something. Tomaru-kun will check it today.

  • ETMY: f3 was stuck.
  • ITMX: It was turned out that BF was not cooled down.
• Type B:
  • BS was recovered and chamber was closed. Health check showed that mechanically everything was OK.
  • Alignment of BS to REFL using ITMY was done.
  • SR2 seems to be OK, but oplev shows something wrong. Will open chamber.
  • SR3 is OK.
• Type Bp:
