(probably very close to O4, because we need ER) * DQR update * no update * Commissioning of GreenX * In the last weekend, the commissioner tried continuous GreenX. During that trials, they found many short term lock loss (~10 ms). 10 ms is too short to follow the suspension motion, so it is likely that there are some causes of the lock loss except for the suspension motion. * The commissioner needs helps DetChar members to identify the cause or give a hint of the cause. * For details, see [[https://klog.icrr.u-tokyo.ac.jp/osl/index.php?r=19963|klog#19963]] [[https://klog.icrr.u-tokyo.ac.jp/osl/index.php?r=19983|klog#19983]] * main channel K1:TMS-X_GR_PDA1_OUT_DQ * time : 2022 Mar 06 23:37:50 UTC = 2022 Mar 07 8:37:50 JST = GPS time 1330645088 ----- === 20220228 (Mon.) === * Agenda * 120Hz glitches * DQ flags for O4 * progress of DQR * lock loss study of GreenX * Minutes (Yuzurihara) * accouncement * LVK meeting March 2022 [[https://wiki.ligo.org/LSC/Meeting/LVKMeetingMarch2022|wiki]] [[https://cgca.uwm.edu/events/2021lvk|web]] * registration is available * Wed, 17 March 2021: * Plenary Session #1 (09:00-10:30 US/CDT) (=3/16 23:00 JST) * Paper Presentation Session #1 * Plenary Session #2 (16:00-17:30 US/CDT) (=3/17 6:00 JST) * Thu, 18 March 2021: * Plenary Session #3 (09:00-10:30 US/CDT) (=3/17 23:00 JST) * Paper Presentation Session #2 * Plenary Session #4 (16:00-17:30 US/CDT) (=3/18 6:00 JST) * Pastavi server will be unavailable tonight * [[https://klog.icrr.u-tokyo.ac.jp/osl/?r=19913|klog#19913]] * 120Hz glitches * no update * DQ flags for O4 * no update * progress of DQR * igwn-alert is running more than 9days and receiving the MDC alert * next step is to connect the MDC alert with the launch TaskManager. * remained task is to develop InspiralRange [[https://git.ligo.org/detchar/dqrtasks/-/issues/8|issue]] * lock loss study of GreenX * [[https://klog.icrr.u-tokyo.ac.jp/osl/?r=19906|klog#19906]] * From the Hveto result, the channel (K1:IMC-SERVO_MIXER_DAQ_OUT_DQ) was the most coincident channel with the lock loss of GreenX. * unify the detchar computing environment (YamaT) * scattered codes and applications (Omicron, summary page, ) over Kamioka computers are troubling. * we plan to unify the environment by using igwn conda * detail will be reported in next meeting * (Darkhan) conda environment on k1ctr*. someone accidentally update someone's conda environment. administrator should prepare the conda environment? * (YamaT) k1ctr* share the environment. this activity is not related to k1ctr* but k1sum[01], k1det[012]. we should separate the user environment and the environment for the DET tools * (Darkhan) should avoid accidental mistake. ----- === 20220221 (Mon.) === * Agenda * 120Hz glitches * DQ flags for O4 * progress of DQR * Minutes * 120Hz glitches * No updates * DQ flags for O4 * No updates * progress of DQR * [[https://klog.icrr.u-tokyo.ac.jp/osl/?r=19847|klog#19847]] * Proposal new tool to see past data by NDS (Darkhan) ----- === 20220207 (Mon.) === * Agenda * 120Hz glitches * Report from [[https://wiki.ligo.org/DetChar/JanFeb2022DetCharF2F|LIGO Detchar F2F Meeting]] * DQ flags for O4 * progress of DQR * Minutes * 120Hz glitches * No updates * DQ flags for O4 * [[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=13851|slide]] * (Yuzurihara) read BLRMS data and made the several plots with 1% and 99% percentile. * When KAGRA will be locked as observation mode? * hopefully after july, there will be lock trial for two monthes(?) * When you set the 1% criteria, always you throw away the 1% data? * We might need to consider the better procedure to care that point. * progress of DQR * [[https://klog.icrr.u-tokyo.ac.jp/osl/?r=19671|klog#19671]] ----- === 20220131 (Mon.) === * Agenda * 120Hz glitches * Report from DQR hackathon * DQ flags for O4 * Master thesis (Morisue-san) ----- === 20220117 (Mon.) === * Agenda * 120Hz glitches * ITMX glitches * DQR progress * DQ flags for O4 * Minutes * 120Hz glitches * No updates * Next step is coincidence search with signals around ETMY including local control sensors. * ITMX glitches * [[https://klog.icrr.u-tokyo.ac.jp/osl/?r=19212|klog#19212]] * K1:VIS-ITMX_F3_LVDTINF_GAS_{IN1,OUT} have glitches. * It seems to occur around AA chassis.
