Report of work (*:responsible person)

• IFO: *Izumi, Enomoto, Nakano + many
  • Michelson lock lasted ~40min with Guardian.
    • ETMX had some drift. It may cause lock down.
  • Modulation frequency was not tuned yet to iMC length.
    • Measurement of AM conversion can know the matching of mod. freq. to iMC length.
  • PR3: Oplev has glitch. The laser source of oplev may be a cause. Needs fiber cleaner to exchange the laser.
• BS: *Eleonora, Izumi, Arai
  • BS IM feed back was engaged.
    • Target crossover was originally 3Hz but actual crossover was limited up to ~0.1Hz, because 1.25Hz peak disturbed control.
  • Gain of some loops of oplev servo changed stronger.
• CAL: *Yamamoto, Enomoto, Izumi
  • Optical measumremnt was measured.
  • Sensitivity is shown in the control room, being calculated from H(t).
• Injection: *Miyamoto, Yokozawa
• Noise budget: *Michimura, Enomoto
• IOO: *Kokeyama, Enomoto
  • MCE trans was clipped. Output PSL was going down to bottom direction, and it was a cause of clipping. This clipping does not affect to IFO control.
• ETMX: *Hasegawa, Nakano, Enomoto
  • ETMX has some drift for 10-20urad.
• ETMY: *Nakano, *Shishido, Ushiba, Miyamoto
  • ETMY need L damping.
  • Gardian was implemented.

Work plan (*:responsible person)

• BS: *Eleonora, Izumi, Arai
  • Opleve loop gains will change stronger.
• CAL: *Yamamoto, Enomoto, Izumi
  • Cal signal will be injected.
• IFO: *Izumi, Enomoto, Nakano + many
  • Measurement without locking morning, measurement with locking in the afternoon.
