=== Agenda ===   * General issue * Interferometer status * Detection range is about 40kpc at maximum * There is still some peaks in the lower frequency * Mostly AS PD noise at higher frequency * Peaks appeared at higher frequency * December 17-24 24h engineering run * [[http://gwwiki.icrr.u-tokyo.ac.jp/JGWwiki/KAGRA/EngineeringRun/ER191217_24/ | wiki]] * PEM festival * 12/13(Fri) 9:00-17:00 * Vibration injection to PSL, REFL and AS table * Vibration to IXC and IYC * 12/20(Fri) * No PEM work * 12/24(Tue) * FFU, cooler, vacuum pump turned off * Conference * JPS (2010/3/16-19 @ Nagoya) * Yokozawa, TTanaka * PEM injection * Shaker injection1 (TTanaka, Yokozawa) * Where is the PZT shaker driver? * Acoustic injection -> Shaker injection * Shaker injection2 (Washimi, Camilla) * Bluetooth shaker + Chromebook * optical table, oplev, ... * acoustic injection (TTanaka, Yokozawa) * PSL, REFL and AS table injection * Analysis is ongoing * magnetic field injection (Niigata Tanaka, Fujikawa, Yokozawa) * Effect of the air cooler magnetic field * AS, REFL table injection * Newtonian noise measurement * Thank you for Virgo PEM member! * Francesca mainly measured the newtonian noise * PEM measurement * Sunday morning : PEM injection * 10th Dec. : Xend environmental check * Someday : Effect of the sound to DARM displacement * Someday : Environmental check around BS (including the POP) * Someday : Evaluation of the table cover * Someday : SR2 and SR3 optical lever (Reflection light from SRM?) * Visitors from LV * Adam, Sheila (-12/13) * Camilla (-12/20) * Each progress * Yokozawa * Short report about newtonian noise measurement(Virgo PEM effort) * Short report about jitter noise at PSL room(Camilla effort) * Current serious noises * Washimi * Lockloss study [[http://10.68.10.87/~controls/washimi/LockLossStudy/|link]] * Volt monitor for the optical table [[https://github.com/gw-pem/kagra-pem/issues/198|link]] * update of [[https://www.icrr.u-tokyo.ac.jp/~washimi/KAGRA/PEM/PEMmap/|PEM map]] [[https://github.com/gw-pem/kagra-pem/issues/195|link]] * Polish-up of Acuostic reverberation time (on-going) * Kozakai * Trigger analysis with silent run * TTanaka(ICRR) * Acoustic injection with FPMI [[attachment:191211.pdf|pdf]] * Fujikawa * Lock loss study [[attachment:FujikawaMTG_191211.pdf]] * fujimopy [[attachment:PEMmtg_191211lock.pdf]] * TTanaka(Niigata) * Magnetic field from air cooler and compressor * Magnetic field injection to AS and REFL table * etc
