The GlueX experiment at Jefferson Lab seeks to map out gluonic degrees of freedom in order to gain a better understanding of gluons and their interactions with quarks towards elucidating the phenomenon of confinement in Quantum Chromodynamics. In order to accomplish this goal the experiment must be able to detect and measure the four-momentum of a large percentage of the photons produced. A key component in the study of these photons will be the Barrel Calorimeter (BCAL).
As a critical component of the GlueX experiment, the BCAL must be fully tested and operational before the beam is delivered to Hall D, the newest experimental Hall at Jefferson Lab. In order to ensure the integrity of the optical light guides attached to the face of every module, cosmic muon tests and LED pulser measurements were conducted to test the uniformity of light transmission. It was found that the modules behaved as expected and that the LED monitoring system was operational.
