| === Minutes === * Pcal/camera developments (Inoue) [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=6051|slides]] * YI will go to LIGO Hanford to finalize the Pcal design and have a review (end of Feb. ~ beginning of March) * Prototype setup of Pcal and camera is made at KEK * The detailed schedule was already submitted to SEO and in general approved (a few adjustments needed with other subsystems) * 20w fiber LASER was already ordered * Transmitter/Receiver modules will be ordered in the next fiscal year * To do things by June * Camera window, Holes position, Weight scale, Wide-range mirror, In-vacuum stage * Measurement of the transfer function of AA/AI filters (Yamamoto,Yokozawa)[[attachment:calibration_meeting_170120.pdf|横澤pdf]] * AA/AI filters are used for all the ADC/DAC so it is important to make sure there is no individual variation * A setup has been made in Dec./2016 for the measurement of the transfer function of AA,AI,whitening filters * The measurements are on-going by Kamioka staff and data are being analyzed by Yamamoto-san * Review of iKAGRA calibration (Michimura) [[attachment:iKAGRACalibrationSummary.pdf]] * iKAGRA calibration was done very quickly so the information (e.g. channel names) was not well shared * For bKAGRA calibration, we should have plans in advance to be shared by related groups/people * Calibration lines (80, 135 Hz) in iKAGRA were decided with no specific reason, but just to be close to UGF ~100 Hz * The actuator efficiency of iKAGRA was measured for the X,Y combined system for DARM instead of each X and Y * It was known that there was a delay between X and Y actuation but it was turned out to be small (by Yokozawa-san) * The models were taken from CLIO ones; It is needed to make new models for bKAGRA * Measurements/modeling of transfer functions for type-A suspension (room temperature part) is expected to be done by VIS (Okutomi-san); but to be confirmed * Measurements/modeling of transfer functions for cryopayload will be done by CRY (Miyamoto-san) * AOB * Yokozawa-san officially joined the Calibration subsystem to work on digital system, hardware injection study, and so on |
