Report of work (*:responsible person)

• IFO: *Izumi, Enomoto + many
  • Michelson lock lasted longer than 2 and half hours!
  • Alignment control from IFO to ETMX was implemented by dithering ETMX.
  • RT models for PR2 and PR3 were down sampled from 16kHz to 2kHz. (Ushiba)
  • PR3 alignment was implemented by baffle signal.
  • ETMX damping might be a cause of lock lost.
  • ETMY yaw damping inclease pitch motion by coupling. It will be improved today.(Ushiba)
  • BS oplev is fed back to not only TM but also IM. (Arai)
• WAB: *Akutsu
  • Heat consumption is estimated well. 10ppm produce 4W and it will be absorbed by WAB and now it is simulated by heater.
  • Equilibrium temperature was 21K.
  • Damping became to strong in low temperature.
• SR: *Mark, Enzo, Tanioka, Kozu
  • Wire of RM was broken on SR3 during tightening clamp. There was no damage.
• CAL: *Yamamoto
  • Line injection is being tested.
  • UGF serve will not be implemented, so change of optical gain is compensated in off line.
• Operaton:

  • Operation wiki page is opened.

  • Operation schedule and emergency contact list is put on the white board in the control room.

Work plan (*:responsible person)

• IFO: *Izumi, Enomoto, Nakano + many
  • Measurement without locking morning, measurement with locking in the afternoon.
