Fast, Low Noise Photodetectors for Nuclear Physics

Current and next generation experiments in nuclear and particle physics require detectors with high signal-to-noise ratio, fast response, accurate energy information and high spatial resolution. This project will investigate a compact detector design that can be operated with very high gain. This detector should provide high signal-to-noise ratio, excellent timing, and position and energy resolution, and should be low cost. Phase I will demonstrate the feasibility of producing a solid-state high-gain photodetector. The high resolution detection of scintillation light will be demonstrated. Further optimization of the technology, including scale-up and implementation in nuclear physics applications, is planned for Phase II. Commercial Applications and other Benefits as described by the awardee: The new detectors should be very useful in fundamental studies conducted for nuclear and high energy physics and astronomy. In addition, these detectors would be useful in commercial applications such as medical imaging, non-destructive studies, and well-logging.
