• 1/27: ITMY is aligned to REFL by IR.

• 1/27: ITMX is aligned to REFL by IR.

• 1/27: Beam position of IR at SR3 is confirmed how far from the center.

• 1/28-29: SR3 is aligned to SR2 center by IR.

• 1/28: Alignment of SR2 -> SRM by IR.

• 1/29: Green beam is injected from SR2 AR surface to Y end PD.

• 1/31: Removing bellows at PR and SR area.

• 2/7-8: OMMT -> OSTM by IR, OSTM -> OMC by IR

• 2/12-15: Closing door for central area, pumping down
  • needs drift monitor for VIS

Note

• Report all the wrok to klog, and gokagra ML if urgent things.
• If you work other location from where it was confirmed at the morning meeting, please contact related poeple.

Report of work

• Type B and COM: SR3 oplev loop was implemented and improved. Motion is much smaller now and it will help alignment work.
  • we saw some oscillation aound 10~Hz
• CAM: GigE camera at POS table to see SR2.
• AOS: TMSY got signal of green at QPD and PD.
• FCL: temperature is between 24-25 degree. Temperature at SR2 is something strange.

Work plan

• MIR: inspection will be done
• AOS: Transportation of NAB in X arm from 11am.
• AOS: We will check BS oplev coupling issue.
• Type B: One of SRM OSEM is close to edge of range. We will fix it today.
