The SENSER CLYC Experiment

The Space and Endo-Atmospheric Nudet Surveillance Experimentation and Risk-Reduction (SENSER) mission launched in December 2021, aboard the STPSat-6 satellite, and is currently in geosynchronous orbit. SENSER is composed of several experimental instruments, including the Hard Radiation Experiment (HRE) CLYC instrument. HRE CLYC aims to evaluate the performance of Cs2LiYCl6 (CLYC) scintillators and silicon photomultipliers (SiPM) in the space environment. CLYC detectors enable neutron and gamma-ray detection within a single volume via pulse-shape discrimination and have been shown to have comparable energy resolution to common scintillators. This experiment will determine if these technologies are suitable for future space applications. This talk will discuss the CLYC instrument and present preliminary data collected during the first 6 months of operation.
