Overview
At the Jefferson Lab (JLab) in Newport News, VA there is an electron accelerator which launches electrons into different halls. Each hall has its own specific targets for the electrons and detecting equipment for results of the collision. In Hall C a high momentum spectrometer and a variety of detectors are used. However, there is no detector for neutral particles. The JLab is creating the neutral particle spectrometer (NPS). One of the major components of the NPS will be PbWO4, a crystal which scintillates, releasing photo-electrons, when hit by particles. These photo-electrons can then be picked up by a Photo Multiplier Tube (PMT) which uses high voltage to allow for the detection of individual photons. It is imperative that the characteristics between the crystals remains uniform.
Goals
1. Collect data on the light yield, transmittance, and refractive index of multiple crystals.
2. Check the data to confirm that the crystals meet the parameters needed for the NPS.
3. Compare the data between different crystals to analyze their uniformity.
