New CdTe Quantum Sensor, With Improved Spatial Resolution, for Fast X-Ray and γ-Ray Imaging
Published online by Cambridge University Press: 10 February 2011
Abstract
We have designed and tested a new compact, very sensitive (>1 μRad), X-ray quantum sensor for high energy (0.5 -10 MeV) flash imaging. Monte Carlo simulations have been computed for several interesting detector materials (CdZnTe, HgI2-a, BGO, CsI, LSO...). From these calculations, we obtain general design rules and curves which allow one to optimize the pixel size of a sensor to the dose levels. An experimental CdZnTe detector array and its performance is presented.
