General issue
- Cooling down
- EX : Achieved 20 K in IM
- Monitored the height by MNV oplev and TCam
The SUM value of MNV oplev decreased with temperature, that turned out the clipping by the viewport of radiation shield klog26232
- Now recovered, but SUM decreasing continued
- Serious frosting and finesse down detected
- Monitored the height by MNV oplev and TCam
- IX, IY, EY ongoing : about 110 K in IM (2023/08/18)
Temperature change url
- EX : Achieved 20 K in IM
- Vacuum level trouble
- EX : performance of one cryocooler became worse
- No serious damage to the test mass
- Plan to restart it around LVK meeting(September)
- Yarm
- Y-21 vacuum trouble
- Now, by turning on the TMP, keep good vacuum level
- Y-21 vacuum trouble
- EX : performance of one cryocooler became worse
- New high power laser replacement
- Temperature drift would be smaller by tuning the temperature control
- But if we increased the output laser power from PSL room, IMC cannot be locked.
- Now operating the current old laser
- Alignment inside the PSL room
- PMC alignment done(No so serious change)
- GR alignment done (Increased the beam power)
- Interferometer operation
- After checking the POP and REFL table again, and found one BS flipped.
- Then, PRFPMI RF became more stable (One night lock)
- After checking the POP and REFL table again, and found one BS flipped.
- New IP control
- Ongoing
- PEM tasks
- Outside magnetometer
- DAQ system trouble? Washimi-san sent to company
- Acoustic noise at OMC
- Re-cabling for OMC speaker
- AC power check at Yend
- SUM value of the MNV oplev decreased
- No problem in AC power supplying
- Outside magnetometer
