Polishing the Ferrules Howard Budd Sep

Polishing Epoxy on the Ferrule We glued fibers in the 10 ferrules that Dave Warner gave us One problem was that for 3 of the ferrules the epoxy backflowed onto the outer edge of the nipple. When it does this the epoxy will flow up to the flat part of the bottom part of the connectors. This means it will not be positioned correctly in the polisher And it will not be positioned correctly in the light detector The epoxy does not chip off easily In does chip off easily in the DDK connectors and Minerva single fiber ferrules (which is delrin, and they are machined.) In thinking about this getting we want a reasonably tight fit of the fiber in the hole to prevent this This is opposite to trying to get good epoxy flow around the fiber

Epoxy Polish We cut the WLS fiber in the back of the this pigtail to try to get the illumination from the from We don’t have any clear 1mm fiber Diamond seems to have sustained some damage
