On January 16, I began to bundle light guides for milling by myself. I put a collar around the fibers at one end, then put another collar on at the same end. Once the second collar was tight, I slid the first collar toward the other end of the fibers. Then I noticed that at certain points there was a gap between the fibers in the bundle and the collar even though the collar was tight. Consequently, a few fibers could slip even though most could not. I brought the problem to Ann Marie and Liana, and Liana came over to fix the problem. Eventually the fibers were tight to our satisfaction.

On January 17, I swept the lab and polished two bundles of light guides. We want to know what dirty fibers look like and how they affect performance. To that end, I took photographs of calcium deposits from straightening and specks from milling on the fibers. Then I helped Ann Marie take more photos. Since there was too much glare on the fibers to take a good photo from directly above them, I shaded the fibers with my notebook while Ann Marie took pictures. Then Ann Marie wanted pictures of light shining through the dirty fibers. She used a green laser. I held the switch to shine the laser and she took pictures.
