Suspension preparation

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
