Vent plans

Prep for next vent

(1) Dichroic mirror for recycling cavities (Jamie)

spec in DCC
wedge angle = 2 deg
quotes:
- ATF
- Laseroptik (final)
  - 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
Optical table layout needs to be modified

(2) Black glass beam dumps (Koji)

Large baffle style covers for the suspensions
Small V-shape pieces for generic purpose
being baked...

(3) OSEM mount screws (Steve)

Hex-top, longer, sliver-plated
Qty = 100
No-plastic
final design
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...

(5) OMC activation (Jenne)

Calculate the mode matching solutions and prepare appropriate telescopes
Draw optical layout
Digital controls

(6) OSEM upgrade (somebody)
