Notes from Putting a Output Filter Cavity in Vacuum Meeting with Masayuki, Gabriele, and Maty

[Torrey, Daniel]
 

Are we going to be limited by laser noise?

Gabrielle suggests we do this in our lab with their vacuum chamber

Initial Pressure Target: 10^-1 Torr, so no turbo

The chamber fits our cavity, but is somewhat dirty so we should clean it

LIGO has pumps, gauges

We might need to supply some flanges

We should use QPDs to measure beam location before and after

These could be in vacuum, but not necessary

To minimize vibrations, we should support the chamber with viton and turn the scroll off while taking data
