Advanced Photodetector for Dark Matter Studies
Optical detectors are a very important component of both existing and future particle physics experiments, including those being developed for dark matter studies. However, for dark matter studies, the expected performance of experimental systems is limited by the properties of presently available optical detectors. This project will investigate new, robust, large-area avalanche photodiodes (APDs) for the detection of scintillation light emitted by liquid xenon, for eventual use in dark matter studies. Phase I will demonstrate the feasibility of applying the new APDs toward dark matter experimentation. The APD photodetector will be built, and its performance in detecting scintillation light from liquid xenon will be evaluated. Detection threshold and temporal response will be measured. Commercial Applications And Other Benefits as described by the Applicant: Over and above the use in particle physics, the new detectors should be applicable to nuclear medicine, space research, homeland security, environmental monitoring, and material science studies
