Commissioning Strategy Meeting (2023/2/17)
- Topics on the sensitivity enhancement
- Seismic noise isolation of OMC?? (~ 6 months??)
- where is the noise due to the "normally expected" seismic noise?
- ..
- 3 mirrors(IX, IY, EY) cooling(~2 months(assuming "1 month for one mirror" and "one cooling in one arm at the same time".)
- How much commissioning time will be used for
- suspension height adjustment
- drifting
- PY/L coupling adjustment
resonance mitigation control in -> minor adjustment is enough, mainly in gain.
- How much commissioning time will be used for
- Control of PRFPMI+DC
- ADS/ASC/WFS for arms to mitigate the contrast fluctuation
- Enhance OMC lock-acquire stability?
- More dynamic range of PNC-X?
- Laser
- HPL usage for IFO (120W to Toyama U, Characterized New 60W to KAGRA)
HPL in Toyama U (new 60W characterization -> KAGRA, Repair of 120W from KAGRA)
- ISS
- Noise hunting and reduction
- MICH
- PRCL
- Suspension control around 100Hz for some suspensions
- Suspension control around the micro-seismic area
- MISC
- Remove unnecessary stuff from the isolated area, especially around OMC.
- Seismic noise isolation of OMC?? (~ 6 months??)
- Topics on maintenance for the long operation
- Vacuum stuff
- Cryo-coolers
- Air conditioning Coolers/heaters
- Seasonal water drainage
