Abstract
Advanced Photon Sources have proven to be outstanding facilities for x-ray diffraction and scattering of non-crystalline biological materials. The biggest problem is finding a detector that can provide multiple frames of detailed structural information, with the required millisecond time scales and extremely high count rates, from third-generation synchrotron sources such as the Advanced Photon Source (APS). Unfortunately, no available x-ray detectors can provide the necessary high spatial resolution, large area, high sensitivity, and millisecond time resolution. This project will develop an x-ray imaging detector that can fulfill these requirements at a substantially reduced cost compared to current detector systems. The detector will be based on two new technologies: (1) a very bright, high-resolution scintillator that offers unique advantages for high speed imaging; and (2) a novel readout that provides millisecond time resolution with significantly improved signal-to-noise ratio than current detectors. In Phase I, the scintillator will be fabricated in a microcolumnar form and its performance will be evaluated under realistic experimental conditions. Scintillator screens will be integrated into a novel readout to form a prototype detector, which will be used at the APS beamline to demonstrate its efficacy for the proposed application. Commercial Applications and Other Benefits as described by the awardee: For time-resolved x-ray-diffraction studies, this detector should provide the large area, high spatial resolution, and millisecond readout needed to overcome the limitations of current instrumentation. Additionally, it should find widespread use in biological imaging, high speed computer tomography, non-destructive testing, and basic physics research. Its high performance, compact nature, and low cost also should make the detector ideal for homeland security applications, ranging from baggage scanning to the detection of biological agents. The estimated market is $25 million per year
