  * 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)
  * ETMY damping filter was back to what was best. Fluctuation is ~1urad.
  * ETMX damping filter changed a bit. Fluctuation is < 1urad.
  * BS alignment noise was improved around 10-30Hz 8 at most.
  * Gain bump can be seen around UGF of MICH.
  * Lock of the last night was ~1hour. Lock was lost because of L to oplev coupling seems to exist.
Line 54: Line 54:
 * 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.
Line 59: Line 55:
 * SR: *Mark, Enzo, Tanioka, Kozu
  * Wire of RM was broken on SR3 during tightening clamp. There was no damage.
 * Camera: Yokozawa, Inoue
  * IYA camera could not see BS, because some clipping may exist.
Line 62: Line 58:
 * CAL: *Yamamoto
  * Line injection is being tested.
  * UGF serve will not be implemented, so change of optical gain is compensated in off line.
 * WAB: Akutsu
  * Heater off.

 * IYC: Tomaru
  * Cooler off.
Line 68: Line 66:
  * Operation schedule and emergency contact list is put on the white board in the control room.
Line 72: Line 69:
 * IFO: *Izumi, Enomoto, Nakano + many
  * Measurement without locking morning, measurement with locking in the afternoon.
 * CAL: Yamamoto
  * Optical gain measurement
  * Open loot TF.
  * Amplitude tuning for injection.
  * Sensitivity.
  * BS to MICH TF, if can.

 * IFO: *Izumi, Enomoto + many
  * Higher BS oplev gain will be tried today by the gain switch on opec board or the gain setting on whitening board.
Line 94: Line 98:

 * week of 4/30
  * Operation continues.
