* For gluing follow the instructions for mixing and pipetting the epoxy. The procedure for applying the epoxy to multiple fibers is very much like the applying to single fiber, that is; inject glue between waveguide and scintillator, gently close the gap between scintillator and waveguide, remove excess run off if there is any, finally verify that the fibers are still in proper alignment.  For a single set of fibers this procedure requires some care and delicacy, for multiple fibers the difficulty increases exponentially. One pitfall to beware of is that the epoxy has a pot life of 30 to 45 minutes, and after allowing time to let the bubbles escape for the freshly mixed epoxy leaves only about 20 to 30 minutes before it should be disposed of.  This should be enough time to apply the epoxy to all the fibers properly, however, if for whatever reason, one of the waveguide/scintillator pairs are now misaligned, there is not much time to make the necessary adjustments. If making adjustments to misaligned fibers takes too long, separate the problem scintillator from the waveguide but do not try and remove anything from the set as that will most likely disturb the other fiber pairs.
