* 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. |
* Leak was caused wrong positioned O-ring. The shape of O-ring was deformed. * Pump down started 15:50 yesterday. * Now vacuum gage shows ~30Pa. * VAC: *Inoue, Yokozawa * Vacuum monitor is ready! except for Y arm monitor. |

* 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. |
* 0.07Hz was damped well! * Yaw and pitch are < 1urad. |
Line 69: | Line 70: |
* 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. |
