* 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. |
* OLG was measured in the daytime. * Error of TF of actuator is ~20%. * 120usec delay exists in the MICH loop. * BS oplev sensitivity was improved by increasing whitening gain. * Longest lock of the last night was ~8hour. * Baffle PD signal is used to BS alignment. * 40Hz periodic noise was seen every 16min. It is air compressor. * It can be stopped during operation. * Timing to IY0 will be connected today. * WAB: Akutsu * Heater was turned off ~10am. * IYC: Tomaru * Cooler was turned off at 4pm and the vacuum level got worse to 1e-3Pa order. |
