It is important to determine light yield of each fiber before shipment to Jefferson Lab.  In order to do this, light yield tests will be performed on each fiber in our dark box using a red laser diode on a pulsing circuit.  The setup of the fibers is very important, as any offset fibers could give an inaccurate result.  It is also important that procedure is followed to prevent damage to electronics.
