DQ Shift checklist

Task No.

Theme

Substance

1.

Check SummaryPage works or not

See https://gwdet.icrr.u-tokyo.ac.jp/~controls/summary/monitoring/
Status should be OK

2.

Check Sensitivity & Binary range transition

See https://gwdet.icrr.u-tokyo.ac.jp/~controls/summary/today/
When you find some transitions, post to klog

3.

Check Spectral line noise (Yesterday)

See https://gwdet.icrr.u-tokyo.ac.jp/~controls/summary/yesterday/detchar/fscan/
When you find new or disappeared lines, post line information (frequency, transition time, etc.) to klog

4.

Check Lockloss data

See https://gwdet.icrr.u-tokyo.ac.jp/~controls/summary/today/
We can get the GPS time list at lockloss (GPS end). See below for more challenging characterization.

5.

Check the input power

The EPICS channel showing the input power is K1:LAS-POW_IMC_DC_OUT_DQ

6.

DQ shift Reports

Post the findings on klog, for example, klog12282

Additional DQ challenge: Lockloss investigation

  • If you have time, please try to find the cause of lockloss by checking the following important channels!
  • Did any suspensions move drastically?
    • Check the following oplev channels:
      • K1:VIS-{PRM, PR2, PR3, BS, SR3, SR2, SRM, ITMX, ITMY, ETMX, ETMY}_TM_OPLEV_{PIT, YAW}_DIAG_DQ (urad) for large suspensions.
      • K1:VIS-{MCI, MCO, MCE, IMMT1, IMMT2, OMMT1, OMMT2, OSTM}_TM_OPLEV_{PIT, YAW}_OUT_DQ (not calibrated in urad) for type-C suspensions.
  • Did any error signals have obvious glitch or saturation?
    • Error signal channels are K1:LSC-{DARM, MICH, PRCL, MCL}_IN1_DQ.
  • Did POP90I buildup (the sideband buildup within the power-recycling cavity, PRC) degrade before lockloss?
  • Which arm did start degrading first?
