Evaluation of Timepix3 Si and CdTe hybrid-pixel detectors spectral performances on X and gamma-rays

Hybrid pixels, XPAD3, photon counting, PCI Express, X-ray imaging, X-ray cam- era,

Since the charge collection in pixel detectors is very close to 100% and the noise is lower than strip detectors (because of the small capacitance at the input of

In order to investigate the evolution of this bremsstrahlung X-rays signal as a function of the deposited energy in the medium, experiments using different beams have been

One important measurement for photon counting pixel detectors is the efficiency between the pixels.. If the threshold is too high, we lose photons because the charges are shared

The main specification for HEP is a fast sparse readout while for x-rays it is the photon counting at high rate and large dynamic range.. The conclusion is that the electronic

In this paper, we investigate the component separation approach with the camera XPAD3 in order to overcome these limits of subtractive K-edge imaging. We first describe the

Some of the advanced diagnostics used in this project to better understand spray formation include: (1) 2D X-ray radiography and 3D X-ray computed tomography obtained from

This demonstrated the possibility of spectral imaging at 55 µ m spatial resolution in a wide energy range using CdTe pixel sensors, with however a detrimental effect of the
