Spring and Summer 2025 Research

Ewan Chattin (UC Physics ‘25), Maddy Hickson (UC Physics ‘26), and Nathaniel Nerone (UC Pre-Engineering ‘27) tested and measured full energy detection efficiencies, energy resolutions, and timing resolutions of 9 CeBr₃ scintillator detectors purchased with National Science Foundation support. These detectors will become part of the CeBrA array of gamma-ray detectors at the Fox Lab at Florida State University, which is used with the Super Enge Split Pole Spectrograph to collect charged-particle gamma-ray coincidence data from nuclear reactions.
