Test and Calibration of the Pair Spectrometer Detectors at the Jefferson Laboratory

The pair spectrometer is a key instrument used to monitor the quality of the photon beam in Hall D at Jefferson Lab. We spent two months in summer 2015 working on the pair spectrometer with a focus in two areas: (1) to test high granularity hodoscopes, (2) to perform the timing calibration by analyzing experimental data collected in the spring 2015 from the commissioning runs. The results and our research experiences will be presented.
