Vent plans

Prep for next vent

(1) Dichroic mirror replacements for PR3 and SR3

spec in DCC
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
optics in hand
phase map of mirror, in and out of tip-tilt mounts
- what resolution do we need? Need to measure curvature.

(2) Active tip-tilts (Suresh/Jamie)

Suresh is going to LHO April 15-25 for assembly/shipping of tip-tilts
tip-tilts:
- tip-tilts from LHO
- bake
- assemble
- add mirrors
- level
in-vac cables (quadrapuses)
- ship parts to RND Cables
- place order with RND Cables
- bake
electronics:
- gather components:
  - DAC
  - anti-image filters
  - dewhite filters
  - coil drivers
  - eurocrate
  - cables
- install
- test in DAQ

(3) Black glass beam dumps

Large baffle style covers for the suspensions
Small V-shape pieces for generic purpose
manufacture
pedestals, clamps?
bake
assemble

(4) OSEM mount screws

requirements:
- Hex-top, longer, sliver-plated
- Qty = 100
- No-plastic
final design
manufacture
bake
ready to install

(5) New periscope plate

manufacture
bake
ready to install
need shorter pedestals for green PBS and beam dump

(6) Cavity scattering measurements? (Jan)

(7) Review IP{ANG,POS} alignment/closeup proceedure

tip-tilt wiring

relevant pictures:

BSC table, from north, above output PZT0: 1, 2
- Do we have 3 available 25-pin connectors on BSC table??
IOO table, from west, through AC, input PZT0 detail: 1, 2
- It looks like we have (or will have) 1 available 25-pin connector on IOO, which is all we need!
OMC table, from east, through AC, output PZT1 detail: 1, 2
- unclear what is available here
