Commissioning the Coordinate Detector for the Hall A Super Bigbite Program

The Super BigBite (SBS) program in Hall A of Jefferson Lab will be conducting multiple experiments to measure and better understand nucleon structure. One detector to be used in the SBS program, the coordinate detector (CDet), is currently being commissioned and uses an array of photomultiplier tubes (PMTs) and scintillation bars to measure the trajectory of a particle that passes through it. The CDet will act as a supplementary charged-particle tracking detector. The goal of the CDet commissioning process is to prepare it for experimentation with SBS by selecting the high voltage values at which the PMTs in the detector are most efficient. Once the commissioning process is complete, the CDet will be able to provide improved tracking efficiency charge for the SBS experiments and, ultimately, help with the understanding of fundamental nucleon structures.
