* 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; * 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 * 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. * DGS: *Yamamoto * Interface card for PCIe on k1ioo was exchanged and connection between RTPC and IO chassis was established again. |
* IFO: *Izumi, Enomoto + many * Michelson gardian was implemented. Lock is identified by the REFL and a tripped state of BS. * Lock lasts typically several of 10 minutes. * PR2 had a jump caused by a DAC glitch once a day. Sampling rate will be lowered? * PR3 also had jumps caused by DAC glitches. * Whitening filter was implemented at demodulated signal of RFPD. Sensitivity will be improved. * Modulation frequency was tuned to iMC length. Optical gain increased 1.4 times. |
