  • Regular meeting meeting

  • Web meeting with Zoom2 (Zoom2)

Agenda

  • General issue
    • Interferometer status
      • Several morning runs were held. They are silent run after the IFO commissioning.
        • We can use the PEM injection and calibration line study in future

        • See the detail in url

        • Silent run -> Some excitation(including calibration line) -> PEM injection -> Hardware injection

        • Current urgent noise
