Prep for next vent

(1) Dichroic mirror for recycling cavities (Jamie)

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 now in hand
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
final design
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

(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)

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