Low Noise, High Rate X-Ray Spectrometer for Synchrotron Applications

X-ray detector arrays with high energy resolution, high sensitivity and high count- rate performance are required for synchrotron beam-line studies. In many studies conducted with synchrotron beam-lines, the characteristics of available X-ray detectors limit the overall system performance. The proposed project aims to investigate a novel low capacitance design for silicon detector arrays that offers high energy resolution, high efficiency, high count-rate operation as well as relatively easy fabrication. This should be very beneficial for X-ray studies conducted at synchrotron beam-lines. The Phase I project will aim to demonstrate the feasibility of producing high resolution, high purity silicon detector arrays with low capacitance. Demonstration of high resolution detection of X-rays with the new detectors is planned in the Phase I project. Commercial Applications and Other Benefits: The proposed detectors will be very useful in X-ray detection studies conducted at synchrotron beam-lines. Additional applications include nuclear and particle physics, astronomy, health physics, nuclear non-proliferation, and non-destructive studies.
