A growing interest has recently been observed in high flux X-ray imaging detectors with energy discrimination or spectroscopy capabilities. In this study we evaluate the performances of energy sensitive CdTe and CdZnTe detectors for X-ray imaging at fluxes of up to 2 in the 20–150 keV energy range.

A growing interest has been observed in energy sensitive pixel array for high flux X-ray imaging. These devices provide compositional analysis of the imaged objects and would be useful in a wide range of applications in the field of security, non-destructive testing and medical imaging. We have developed a CdTe linear array pixel detector for energy sensitive X-ray imaging that can operate at several...

A growing interest has recently been observed in energy sensitive pixel array for high flux X-ray imaging. These devices provide compositional analysis of the imaged objects and would be useful in a wide range of applications in the field of security, non destructive testing and medical imaging. CEA-LETI has developed a CdTe linear array pixel detector coupled with a novel 16-channels fast readout...

This paper presents multi dimensional approaches for material identification applied on experimental X-ray measurements obtained with CdTe spectrometric detector. LETI has been developing a 16 channels fast read-out electronics capable to perform spectrometric measurements at count rates above 107 counts/s. The read-out electronics was coupled to CdTe linear array pixel detectors. A multidimensional...

The development of a novel energy resolved fast X-ray imaging detector is reported. The device is based on pixellated cadmium telluride (CdTe) and cadmium zinc telluride (CdZnTe) detectors coupled to a custom designed 16-channel fast spectroscopy front-end electronic circuit. For each channel, a fast Analog to Digital Converter (ADC) continuously digitizes the signal from the detector pixel. A FPGA...
