High Performance X-Ray Detectors

X-ray detector arrays with high energy resolution, high sensitivity, and high count rate are required for synchrotron beamline studies. In many studies conducted with synchrotron beamlines, the characteristics of available X-ray detectors limit overall system performance. This project will investigate a novel, low capacitance design for high purity silicon detector arrays, which offers high-energy-resolution, high-efficiency, and high-count-rate operation, as well as relatively easy fabrication. Phase I will demonstrate the feasibility of producing high-resolution, high-purity, silicon detector arrays with low capacitance. A demonstration of the high-resolution detection of X-rays with the new detector arrays also is planned. Commercial Applications and other Benefits as described by the awardee: The new detectors should be very useful in X-ray detection studies conducted at synchrotron beamlines. Additional applications include nuclear and particle physics, astronomy, health physics, nuclear non-proliferation, and non-destructive studies.
