* Large leak was found but it is not identified where it is. Currently Vacuum level is 200Pa, but it should be around 0.1Pa if no leaks. | * 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. |

* Damping for yaw woks somehow and RMS is ~0.2urad. * A very high Q peak was found on pitch and it takes several hours to be calm. This high Q seems to be Sphere parts. * ETMY: :Miyamoto, Shishido * No progress for damping. * ETMY: *Okutomi * ETMY TF was measured. Not only 2 but all F1, F2, F3 seem to be locked. Moving FR may fix the lock. |
* 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. * ETMY: *Nakano, Shishido * 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. * BS: *Eleonora, Izumi * We are optimizing diagonalization of L2P filter. Needs more time. |

Report of work (*:responsible person)
- VAC: *Kimura
- 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.
- ETMX: *Hasegawa
- 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.
- ETMY: *Nakano, Shishido
- Yaw dampins seems to be OK. Coupling between pitch and yaw exists. After ~10min or so, oscillation starts up to 10urad.
- IFO: *Enomoto, Izumi
