  * Vibration Isolation,
   * Restarted the BS realtime model.
  * Alignment and Vibration Isolation: Izumi, Okutomi
   * Searching optimal position of IP of ETMY resulted that the stiffness (DC response level) is the same as what it was measured in the air. Still something at lower stage might be hitting somewhere.
  * Mirror view by Tcam also moved by 6mm order! It means that the calibration of LVDT can be wrong by factor of 25.
  * The result of fine tuning showed 1mm off to -x direction.
Line 62: Line 64:
  * Alignment: Izumi, Okutomi
   * ETMY transfer function has a different shape from what was measured before in the air. It means that ETMY might be touching somewhere.
    * For vertical, below BF transfer function seems to be OK.
    * Yaw might be rotating too much.
     * After 1/17, ETMY started showing something strange. Stiffness changed gradually, but Q did not change much.
 * Vacuum: Kimura
  * Another leakage was found with 1e-8 order (2 order of magnitude larger than other two). We leave it anyway and we will start cooling.
Line 71: Line 69:
  * Alignment: *Izumi, Okutomi
    * We will rotate IP yaw to release somewhere touching. This work takes 1day at least.
    * Detchar for spectrum of suspension is necessary as soon as possible.
  * Cooling: Kimura, Suzuki, Yokozawa
   * We will start cooling around 11AM.
Line 75: Line 72:
  * Vacuum
    * Gate valve will be closed today.
    * Needs 2days for evacuation. If once evacuated, cooling will be late ~2weeks.
 
  * Type B
   * SR assembly continues.
  * Alignment: Izumi, Miyakawa
   * Oplev of ETMY will be monitored at the control room, and misalignment will be restored remotely during the cooling.
Line 82: Line 75:
 * Laser hazard: PSL. At some in this evening, it will be the are over the SR line for double-checking the IMC alignment. Kokeyama is responsible for it.   * WAB cooling test: Akutsu
   * Temperature monitors are being prepared.
   * Oplev is ready.

 * Laser hazard: PSL. Green will be used all the day, then the center up to PR3 will be the hazard area.
Line 86: Line 83:
   * Finding causes of ETMY trouble.
    * Evacuation might be needed if ETMY is touching somewhere.
    * Cooling also will be delayed for 2weeks or so.
    * 2/7 Cooling.
Line 91: Line 87:
  * The ETMY mirror showed a strange scattering pattern.   * IP drifted 2mm in the air, and another 2mm when pump down.
