Detector characterization for particle-gamma coincidences at the Super-Enge Split-Pole Spectrograph (SE-SPS)

Highly efficient 2”x2” and 3”x4” CeBr3 gamma-ray detectors are currently being tested at Florida State University to arrange them in a modular array for particle-gamma experiments at the Super-Enge Split-Pole Spectrograph (SE-SPS). The coincidence timing between the anodes of the focal plane detection system and the detectors has already been established with a 228Th calibration source. Furthermore, we characterized the CeBr3 detectors determining their energy as well as prompt timing resolution. To add to the ancillary detector systems at the SE-SPS, four Passivated Implanted Planar Silicon (PIPS) detectors of different thicknesses were also tested. Eventually, these are envisioned to be used for internal conversion electron detection. An overview of the different tests and results will be given.
