* 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. * 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) |

* 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. |

* PR3: Oplev has glitch. The laser source of oplev may be a cause. Needs fiber cleaner to exchange the laser. | * Wire of RM was broken on SR3 during tightening clamp. |

* 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. |

* 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. |
