* 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: Aso, Takahashi, Ohishi, Miyo * We opend the chamber and we confirmed that the height of PR2 and PR3 were not at the wrong point. * LVDT had jump several times in the past, so absolute position of LVDT is not trustable. * It means that the beam changed upstream PR like IMMT, or MC. * We absolutely need monitors to check beam position at all the mirrors. * Alignment and ETMY: *Enomoto, Ushiba, Miyamoto * Beam shift at the PR2 was large ~1cm, and the beam was clipped at the PR3 ~10cm. * Damping of pitch is still under investigation. TFs of pitch role etc. are dirty. |

* 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 which showed the correct IRIG-B ~12 was found. We will replace the current one to the new good one. * It was noticed that MC and FSS shows something wrong this morning. We will check it before changing IO chassis. |

* 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. |
* CRY: mirror temperature ~100K. |

* ETMY: Enomomoto, Ushiba * Check the glitch with the 2kHz model. * Original REFL port will be tested to pick up Mich signal. |
