-Flexures installed SN 21, SN 22, they have survived throughout the day (I haven't unlocked the CRS since moving to the table, but visually they look fine)
- I re-balanced the CRS so there is now a new distribution of masses on the proof mass
-The CRS is semi-bolted on the table, we haven't put any dog clamps down, but there is one place where the CRS can be bolted directly into the table
-Temperaraly put baffles on, on baffle SN 001 had to remove one of the bolts to fit it around a pre-existing optic on the table
-Fil, Mitchell and I got the out of vacuum fiber all cabled up, however, later in the day when we tested the laser power at each point of the chain, it looked like light wasn't making it through the fiber. We have been using this fiber for testing chamberside so if it's an issue with the fiber it started today.
-We turned on the laser briefly to look at the power at each point along the chain:
OUT OF LASER: 20.5mW
OUT OF VAC FIBER: 7um
Which means there's either a issue with the 27m out of vac fiber, or the connector between the laser and the fiber
The plan for Monday is to first switch out the connector and hope that was the issue. If that doesn't fix it, I'll look for another temperary fiber to use to at least get the HoQIs aligned and deal with the broken fiber later.
We did use the long 27m patch fiber for chamberside testing, and it worked well.
There is an other 5m PM fiber on the cart nearby you can use to verify if it's a problem with the connector or the fiber itself.
I would also inspect the fiber ferrules of the long fiber with a fiber microscope to check for damages.
