    Post Observation Activities : OMC noise injection and so on


For shifts for ER and OBS


Observation : Points to Remember

  • Basic
    • Any problems during Observation will be discussed by Miyoki, Yamamoto, Ito and related group (and SEO members) and we decide the directions. Please report these 3 persons and in "klog" if you notice any problems.
    • If we encounter violent ocean conditions, temporal down of IFO will be selected.
    • Daily morning meeting won't be held during Observation to avoid dense situation. Daily necessary information including from office staffs will be sent via e-mail during 9am-10am.
  • Expected Improvements compared with the previous ER and OBS
    • CAL injection reliability
      • Injection failure is improved ?
    • Initial oplev (mirror alignment) condition at the starting point of relock process
      • Alignment recorder is installed at proper timing during lock acquisition ?
    • ADS/BPC situation
      • Whitch are effective, which should be postponed ?
    • IMC angular control
      • Successful ?
    • ISS stability
      • Improved ? , applying timing is changed ?
    • Expected kick at the unlock timing, and known annoying excitation of a suspension system.
      • Guardian is implemented.
    • Off load status for each suspension.
      • Done according to klog ?
      • How about OMC suspensions ?
    • Summary page reliability is enhanced ?
      • improved ?
    • SAL (monkey) Alignment reliability
      • Dewhitening that might contributes a bit to sensitivity should be included or not ?
      • When should we try SAL (monkey) alignment ?
      • How much IMC output power should be selected ?
    • Additional sound proof for bellows
    • Others
  • Actual tasks during OBS
    • Shift Member Duty and Manual :
      • Basic monitoring and recording (by Miyakawa)
        • Manual (important check points)
    • Maintenance Day Activities (from CAL, DGS, FLC/SAF etc groups)
      • SAF/FCL: Weekly SAF/FCL check will be held in the morning on Tuesday (Furuta, Hayakawa, Yoshimura, Kamioka-mine company)
      • DGS:
      • CAL:
    • Restricted Remote Access (from T.Yamamoto)

      • We plan to stop the access to controls@k1gate again from 17:00 on 4/7.
      • If you face some emergency, please use your personal accounts in order to login DGS network.
      • I ask you to use these personal accounts only for a emergency response.
      • If you need remote access to know the site situation, subsystem status, etc as a daily check, please join to develop remote access tools such as SummaryPage, pastavi etc.

      • Unfortunately, some people probably used these accounts for daily monitoring not for a emergency response during previous run. But we need reliable observing data at least during the observing run.
