Weekend

Report of work

• TMS installation started at ETMY.
• Pressure of ITMX was recovered by changing cryo valve at duct cooler.
  • Needs finesse measurement for X arm.
• PRX (PRM+ITMX) was Locked yesterday.
• Michelson was Locked using AS port first time.
• PRMI might be locked last night.
• Sweeping modulation frequency to minimize RF-AM conversion.
• Coil balance for 4 type A, and measuring TF.

Work plan

• DGS: maintenance for installation whitening filter for iMC. iMC will be stopped.
  • Dolphin issue will be fixed today.
