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
- Removal of the photodetectors from the optics tables: REFL33 (PD2), REFL199 (PD6), REFL166 (PD11), AS166 (PD1), AS133 (PD9), POX33 (PD3), POY33 (PD4), PO133 (PD7-8), PO199 (PD7-8)
- Replacement of the diodes: 2mm PDs for REFL11 (AM Monitor PD), REFL33 (PD2), REFL55 (PD6), AS55 (PD9) , POX11 (PD3) , POY11 (PD4); 1mm for REFL166(PD11), AS166(PD1), POP22-POP110(PD7-8)
