FSS path setup
MichaelR, JanP, RickS

Yesterday, we continued the work on the FSS path alignment.

We found that the EOM mounting base did not allow it to get to the 10 cm beam height so we replaced it with a modified iLIGO base.

Here are the powers we measured:

power at input to the FSS power adjust PBSC 400 mW
power downstream of PBSC 20 mW
power at base of FSS periscope 8.5 mW

visibility (measured with drive to EOM disconnected)
(160-60)/160 = 63%
