* One of the small leak was found where it was, but another large leak seems to exist. Leak hunting will last today. * There are 3 ways to the operation in the newt week; * Leak location will be found and fixed without vent. -> ETMX gate valve will open, no delay. * Leak location will be found and not fixed without vent. -> Vent on Wednesday and Thursday, fix leak on Friday, pump down on Friday. -> ETMX gate valve will open, delay for several days. * Leak location will not be found and not fixed. -> ETMX gate valve will not open, no delay, but it will be difficult to find beam at ETMX. |
* Large leak was found at the door on the cross tube, and started venting ~15:00. It takes almost one day to start fix the door, will be afternoon today. Pump down will start tomorrow morning. * Leak test will be performed on Sunday morning. |

* TF for MM coupling of photo sensor was found. * RMS motion seems to be OK if the mirror is not kicked. Even if the mirror is kicked, damping speed is ~10min or something. |

* Yaw dampins seems to be OK. Coupling between pitch and yaw exists. After ~10min or so, oscillation starts up to 10urad. * IFO: *Enomoto, Izumi * Trial lock of Michelson did not succeed because of too much motion of ETMY. |
* One of the 1.64 and 1.66 Hz peak was suppressed but other one was not. 1-2urad in yaw, 10urad in pitch. * RMS motion at REFL port is still dominated by ETMY. |
