Vent plans
Prep for next vent
(1) Dichroic mirror for recycling cavities (Jamie)
- wedge angle = 2 deg
- quotes:
note: 2 deg wedge quote has Fused Silica grade F = 5 ppm homogeneity & micro roughness 0.3 nm RMS, Rana OKed both, 3 wks delivery, Jamie takes care of ordering
order placed... (ETA still unknown)
(2) Black glass beam dumps
- Large baffle style covers for the suspensions
- Small V-shape pieces for generic purpose
being baked...
(3) OSEM mount screws
- Hex-top, longer, sliver-plated
- Qty = 100
- No-plastic
manufactured and being baked...
(4) Active tip-tilts (Suresh/Jamie)
- to get:
- Tip-tilts from LHO
- Electronics
- Cables including vacuum-compatible ones and the non-vacuum ones
- Prepare mirrors
- Assembly and baking
- Prepare feedthrough connectors
- Digital controls
Suresh is going to LHO April 15-25 for assembly/shipping of tip-tilts...
(5) Mode-matching telescope adjustments (Jenne/Suresh)
- Need to determine what exactly the problem is.
- What needs to be moved?
(6) Cavity scattering measurements? (Jan)
