Most of today was spent with me trying to figure out the lensing mentioned in previous update log. Turns out, I was not suppose to mirror the EY setup exactly. Dang, my fault. So I reverted back to the original layout (D1201448) but with an added path for the LED source. I realigned back to ALS-M11 and placed the lenses very roughly in their positions according to T1000717. HWS-L2 (PLCC 1" roc257.5) seemed to make the beam much larger than the diameter of HWS-M1, the next optic. This seemed to be the case unless I placed the lens very near the M1 mirror, but ~400mm away from where T100717 says it should be.

Tomorrow we will work on more of this mode matching before moving on to replacing ALS-M11 with the PBS. If all else fails I would at least like to have this in place so when the arm is opened, HWS work won't hold back commissioners too much.

Attachment 1 - My proposed layout, though due to space it was slightly changed.

Attachment 2 - Current layout.

Attachment 3 - Current layout side view.
