| * KAGRA interferometer status * PRC loss was large, birefringence effect? * FPMI or SRFPMI or DRFPMI * Open the CS area and remove the PRM and SRM? * Before that, we want to investigate the scattering effect at CS area * Chrome Book project * Portable PEM researcher * Spectral analyzer, sound recording, ... * USB accelerometer ([[attachment:20190628_summary.pdf|Center area]]), microphone, ... * Data sharing [[https://drive.google.com/open?id=1zIturCCaSe7mmP0s15TcRzHsvNvomP5k|GoogleDrive]] * Weekly PEM measurement * Friday is temporal weekly PEM measurement * Understanding the effect of the instruments and so on * Power supply * duct vibration * PEM DAQ sampling rate * Due to the limited DAQ power, almost all PEMs are taken at 2kHz sampling * Only PSL and CS microphone are taken with 16kHz sampling for the noise hunting * PEM injection * Shaker injection1 (Yikang, Yokozawa) * Shaker injection2 (Okutomi, Fabian) * acoustic injection (TTanaka) * magnetic field injection (Yikang, Yokozawa) * RF injection (TTanaka, Washimi) * 1st engineering run * 1st engineering run : Jun. 8th 12:00-18:00(JST) : Xarm cavity * Preparing toward the next engineering run * Next engineering run : 13th Jul. * Interferometer configuration ? * English meeting * We will have a monthly English meeting(Mainly share the information with Virgo people) * The third Tuesday of every month 17:00-(JST) 10:00-(CEST) * 2nd meeting will be held at 16th Jul.(Tue) 17:00-18:00 [[http://gwwiki.icrr.u-tokyo.ac.jp/JGWwiki/KAGRA/Subgroups/PEM/Meeting/190716/Agenda|URL]] * Seismon issue * We already installed to KAGRA system * Need the tuning for the KAGRA * Large earthquake happened this month, we "should" be a safe mode before coming large earthquake (PEM issue???) * Task list toward the O3 * [[https://docs.google.com/spreadsheets/d/1DSltWg18KrwnfkVJmSm09TkQ82aQ5lHAdaC9uCozGC0/edit#gid=1072504162|task sheet]] * Please send e-mail to me if you have comments. * each member progress |
