Changes

On January 8, I went to the machine shop with Jon to pick up a milled bundle. I put a bundle on the Unistrut bar to be straightened, and I cleaned some fibers that Jon had polished.

On January 13, I polished bundles of sci

On January 13, I polished bundles of scintillating fibers. It was helpful sometimes to have some static cling between the fibers and the collar.

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.
