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
