Vent plans
Tasks for Vent of Nov 2018
Primary objective - carry out upgrade of the vacuum control system to Acromag
- Do we have necessary hardware?
ii. Steve has acquired some test Serial->Ethernet converter, needs to be checked and interfaced.
Secondary tasks - depends on how many chambers we want to open
- ETMX suspension cage yaw rotation.
ii. SRC length adjustment to allow Signal-Recycled locking.
Tasks for next vent after Aug 30 2017 - not in any particular order
- Installing new RC folding mirrors, PR3 and SR3 (we need to get the actual optics + new Tip-Tilt suspension design)
- Flip existing PR2 and SR2
- Installation of Ruby standoffs for selected optics (we need to get a better magnet gluing fixture ready)
- MC1 suspension inspection and fixing
- ITMX magnet re-gluing
- Baffling (?)
- Installation of steering mirrors to facilitate viewing of optic faces with GigE cameras
- FC cleaning
Prep for next vent
(1) Dichroic mirror replacements for PR3 and SR3
- 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? Need to measure curvature.
(2) IO 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
