Here is a quick summary of the work that happened this week in the optics lab to start populating the VOPO Injection Platform.

We:

* located all of the VIP components (thanks to Betsy and others!)
* gathered and cleaned all of the optics that are needed (picture)
* started assembling the optomechanics
* started gathering parts to set up the laser path to make measurements of the SQZ Faraday throughput and isolation

So..all good.

Note: All of the OFI parts that were sitting on the table have been grouped in a corner of the table.

Following the PR3 issues over the weekend, Jeff and I noticed some minor issues with the SWWD MEDM screens.These were:

the three HAM suspension OSEM face/top channels labeled F instead of T

some ADC monitors on the 4-to-1 screen had copy-paste errors

Quad suspensions did not show the ADC reordering (left-right-side are actually side-left-right on these systems)

I corrected these errors, which required some ADL changes and some macro substitution TXT file changes.

Screenshot attached.

I measured the laser power at the base of the periscope this morning.  The power meter was located
in front of the mirror directing the beam upwards.

    With an Ophir PD300-3W-SH power meter (S/N 171141, P/N 1Z02411), the highest value measured
over a ~2 minute interval was 160.4 mW.

    With an Ophir 20C-SH power meter (S/N 1711175, P/N 7Z02602), the highest value measured over
a ~ 2 minute interval was 169 mW.

    Both readings were taken using a 10 second average, with the zero offset removed using the
Vega display unit.

Siddhesh and I B&K Hammer'ed the new MC2 and PR2 Scrapper Baffles, SR2 Cage, and of Primary/Final/Large? in-vac TCS Steering Mirrors in BSC2. More details, pictures, and results to follow.

Notes for myself later: 
- SR2 cage accelerometer was oriented with X Y Z aligned with the IFO global coordinates. 
- All other measurements had acc Y aligned with IFO Y, and acc Z aligned with IFO X.

Today, Travis and I used the red visible AUX laser to final align the ITMY elliptical baffle and the BS AR and HR baffles.  (Note, we had already done the BS baffles and the ITMX but wanted to check and document.  Note, the front back, and center targets of the elliptical baffle boxes do not all exactly line up, but the tolerance is 7mm so we are center to better than that on all of them.

Also, note, the BS baffles do not look very centered on the mounting to the BS structure, but the beam is centered thru the baffle, so can't do much about that.

Pictures are attached.

This afternoon, while helping Jason install the new AWC optics, I worked on routing the AOSEM cables for the OFI.  Hugh had preassembled the D1000225 SRS cable to the D1000234 Quadrapus cable and mounted it in a cable table bracket.  So all I had to do was route it all on the table, plug it into the feedthru and start connecting AOSEMs.  I've plugged in 1 AOSEM and will start looking at medms next.
