Afternoon

• ALS sweep to find IR resonance (MN, VF)
• Start X-End cryocooler (Yamada, TakahashiM)
• Implement BF stage control on ALIGNED state on type-A guardian (Kokeyama)
• ISS servo setup and OLTF measurement (Yoshioka, Kuromiya, Yamamoto)

• Serial number check of OpLev SLDs.

• Xend - Photon calibrator BIO card fix (Inoue) Done
• Pcal injection test (Inoue) Done ?
• Alert monitor grace DB in Mozumi computer room (Urchen) not yet ?
• Fabian and Shimode-san will check the temperature raise, analog WD, etc for the coil driver change Done

Evening

• ALS sweep to find IR resonance (MN, VF)

Weekend

• IFO configuration guardian (Kokeyama, Saturday)
• Modification of the IMC servo (Enomoto, Sunday)

• Transition to IR (Nakano, Valera, Sat & Sun)

• TF measurement of Type-A (Saturday morning)
• ITM actuator efficiency measurement (Sun morning ?)

Morning (Monday)

• SR3 OSEM check (Fabian)

Standing issues

• Try FPPRMI: with stable 3f signals and ALS extra range, FPPRMI may fix the glitches?
• X end cry cooler replaced. EX frige can be operated. Plan to be decided tomorrow.
• DGS maintenance maybe better on Monday morning?
• Fast shut off feature on type-A after lockloss not to ring (real time model change, Stefan)
• Y-arm lock
  • ETMY suspension control

    • L2Angle decoupling Done

    • ETMY coil driver range increase Done
  • ITMY damping
    • One IM magnet is broken. Need a different strategy. Use MN ?
• DRMI lock stability
  • Model HOM-PHD signal distortion (Aso, Kokeyama)
  • Search for better Gouy phase in PRC
• Initial alignment automation (Nakano)
  • On going
• IFO configuration Guardian (Kokeyama)
  • On going
• Type-A related
  • Implement BF stage control on ALIGNED state on type-A guardian (Kokeyama)
  • United Guardian for all 4 suspensions (Okutomi)
• Type-B related
  • SR3 Yaw motion is too large
    • Different ground level between the IO chasis and the AA filter box may be the reason
    • Replace the DC power supply
• Type-C related
  • OSEM characterization for OSTM (on going, Takahashi)
• OMC
  • Check the OMC on the AS table
• Laser safety
  • Debug the laser safety guardian (Nakano)
