* Alignment and ETMY: *Enomoto, Ushiba, Yamamoto * Beam was lost at the ETMX and ETMY. We will check actual beam inside the chambers at the center area. * Sampling model of RT model was changed from 16kHz to 2kHz and glitches disappeared! |
* Height change of PRs: Tomaru, *Aso, Takahashi, Ohishi, Miyo * We opened the PR2 and PR3 chamber and we confirmed that the height of keystone and mirror of PR2 and PR3 were not at the wrong point. * PR2 was within ~1mm range and PR3 was ~5mm range from the center line. The height of RP3 was changed a bit by fishing rod, and we did not change PR2. * Fishing rods worked well and still were within the range. * LVDT seemed to have jumps several times in the past, so absolute position of LVDT is not trustable. * Recorded the current height and current value. * It means that the beam changed upstream PR like IMMT, or MC. * We absolutely need monitors to check beam position at all the mirrors. |

* IO chassis has been replaced but it did not work due to PC's problem. The PC was replaced and seemed to be OK. but IRIG-B showed 9999xx still. | * A good IO chassis changed and everything seems to be OK now. |

* CRY: mirror temperature ~110K. * The satellite amplifier has an oscillation for photo sensors at low temperature. Satellite amplifiers which will be used for photo sensors at low temperature should be modified. |
* AOS: * Lasers of oplev will can be dying soon. * The lifetime is about 100000h. * Camara: Yokozawa, Inouse * We tried to see BS using Tcam at IXC, but we could not see the BS even with an illuminator. This may be because of the limit of area of viewport on the gate valve. * CRY: mirror temperature ~94K. |

- Fishing rods worked well and still were within the range.
- LVDT seemed to have jumps several times in the past, so absolute position of LVDT is not trustable.
- Recorded the current height and current value.
- It means that the beam changed upstream PR like IMMT, or MC.
- We absolutely need monitors to check beam position at all the mirrors.
- IOO: kokeyama
- A good IO chassis changed and everything seems to be OK now.
