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:
- Hex-top, longer, sliver-plated
- Qty = 100
- No-plastic
manufactured
baked
Ready to install
(4) Active tip-tilts (Suresh/Jamie)
Suresh is going to LHO April 15-25 for assembly/shipping of tip-tilts
- tip-tilts:
We have tip-tilts from LHO
baked
assembled
- add mirrors
- level
- in-vac cables (quadrapuses)
Must place order with RND Cables
- electronics:
- gather components:
- DAC
- anti-image filters
- dewhite filters
- coil drivers
- eurocrate
- cables
- gather components:
(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)
