Suspension preparation

StatusTable.png

Green team

  • before vent

    • relocation of existing optics at the end table -take 1.5day

  • during vent

    • PLL measurement (9 Mar - 9? Apr)
    • set up the green stuff onto the end table
    • align the green laser to the cavity
      • how to: visual alignment
    • mode matching of the green laser to the cavity

      • on the table / corridor projection test ==> sliding mount

  • after tank evacuation

    • recover IP-ANG and optical levers

CDS team

  • 2/22-3/5 Delivery of some computers? / CDS software installations?
  • -3/31 Installation for some of the suspensions?

RF team

  • Conversion of the RF Photodetectors as in the table here
