Vent plans
Prep for next vent
(1) Dichroic mirror for recycling cavities (Jamie)
- 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
- phase map of mirror, in and out of tip-tilt mounts
what resolution do we need?
(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
- requirements:
