In many studies conducted with electron beam systems, the characteristics of available X-ray detectors limit the system performance. This project will investigate a novel low-capacitance design of high purity silicon detectors, which offers high energy resolution, high efficiency, high count-rate operation, and easier fabrication. Phase I demonstrated the feasibility of producing high resolution, high purity silicon detectors with low capacitance. Phase II will optimize the detector design and processing aspects, as well as electronic readout and data acquisition aspects.

Commercial Applications and Other Benefits as described by the awardee: The detectors should be very useful in X-ray detection studies conducted with electron beam systems. Additional applications include nuclear and particle physics, astronomy, synchrotron studies, health physics, nuclear non-proliferation, and non-destructive studies.
