This week FC1 (Filter Cavity [mirror] #1) was installed in the @LIGOWA's new HAM7 vacuum chamber for the new @LIGO A+ Filter Cavity.
FC1 is a triple suspension mirror. This work was also installed in @LIGOWA's NEW "Mega Cleanroom"!

Here the HAM7 #vacuum chamber is partially opened up. The FC1 suspension is shyly hiding inside it's protective cover as TJ (Lead Operator), Travis Sadecki (Operations Specialist), & Rahul Kumar (Suspension [SUS] Detector Engineer) prepare for installation.

This @LIGO Triple Suspension currently has a "dummy weight" suspended at the bottom, this "dummy" will be replaced with its mirror next! TJ is in this photo.
