* Now interferometer is post-observation * It may continue to end of June * Request 1 day for PEM injection * IMC scattered light check by GigE camera (6/30 Kokeyama, Yokozawa) * Check the OMC leg vibration * 6/25 early morning PRFPMI lock with better alignment -> If you interested in, you can use data * Earthquakes at Hida area is serious * Frequency was reduced * Earthquake in Japan is frequent, suspension master guardian worked well * Schedule for O4 will be discuss later * Tasks for post-commissioning * Acoustic injection * 6/5 : Day 1 : For only REFL (remote work) -> study of nonlinearity & up/down conversion -> DAQ trouble * 6/11 : Day 2 : re-measurement of Day 1 (REFL) + PSL * Unclear : Day 3 : BS, SR, ITMX '''<<Before DRFPMI study (Jul.)>>''' * Scattered light * One of the hammering test (lower priority, open the chamber and check) * OMC chamber vibration RMS (lower priority, open the chamber and check) * IMC scattered light by GigE camera (Explained avobe) * Line noise investigation by PEM * No action from DAC, SEO and noise budget team. Maybe skipped. |
