Vent plan for July 2011

Overview

Optimize cavity lengths: PRC, SRC, MICH, arms, etc ([:IFO_Modeling/RC_lengths])
Extract Y green beam from vacuum
Align pick-off port: POX, POY, POP
Align IPANG QPD (eliminate clipping)

Maybe:

Adjust OSEM rotation to minimize unwanted couplings
Install green light beam dumps

More detail

Move ETMs back (How much? How do we know they're in the right place?)
Move ITMs back (How much? How do we know they're in the right place?)

vent preparation check list

Measure all cavity lengths
Align Y green beam
Reduce power to mode cleaner (appropriate level for in-air MC locking)

VENT
