 * IFO: *Izumi, Enomoto, Nakano + many
  * Michelson lock lasted ~40min with Guardian.
   * ETMX had some drift. It may cause lock down.
 * 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)
Line 60: Line 54:
  * Modulation frequency was not tuned yet to iMC length.
   * Measurement of AM conversion can know the matching of mod. freq. to iMC length.
 * 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 63: Line 59:
  * PR3: Oplev has glitch. The laser source of oplev may be a cause. Needs fiber cleaner to exchange the laser.  * SR: *Mark, Enzo, Tanioka, Kozu
  * Wire of RM was broken on SR3 during tightening clamp. There was no damage.
Line 65: Line 62:
 * 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
  * Line injection is being tested.
  * UGF serve will not be implemented, so change of optical gain is compensated in off line.
Line 70: Line 66:
 * 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.
 * Operaton:
  * [[KAGRA/Commissioning/Phase1/Operation|Operation wiki page]] is opened.
  * Operation schedule and emergency contact list is put on the white board in the control room.
