| * 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. |
* Alignment and Vibration Isolation: Izumi, Miyakawa * Drift by cooling is smaller than that of pump down. |
| Line 64: | Line 62: |
| * 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. |
* Cooling: Kimura, Suzuki, Yokozawa * 4k cooler, 50k cooler started. * PLC values are not available. |

| * Alignment: Miyakawa * We keep the eye on the oplev response and correct the alignment if drift is much. |

| * Cooling: Kimura, Suzuki, Yokozawa * We will start cooling around 11AM. * Alignment: Izumi, Miyakawa * Oplev of ETMY will be monitored at the control room, and misalignment will be restored remotely during the cooling. * 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. |
* Laser hazard: All area related to inside the vacuum. |

| * IP drifted 2mm in the air, and another 2mm when pump down. |
