Autonomous and Adaptative Cyber-Physical Systems (ACPS) represent a new knowledge frontier of converging “nano-bio-info-cogno„ technologies and applications. ACPS have the ability to integrate new ‘mutagenic’ technologies, i.e., technologies

High-energy X-ray photons are generated by linear accelerators or flash X-ray sources. These pulsed sources produce a high number of photons in a very short time (from a few picoseconds to a few microseconds). CdZnTe detectors are well suited to dete

Challenges for the design of quantum sensitive 2D imaging detectors for high-energy photons are reviewed. Conception rules and universal data plot are presented. They allow the optimization of pixel dimensions versus incident fluence and the contrast

We are studying the characteristics of a pixellized CdTe detector for high energy imaging applications. We model analytically the spatial response of this kind of detector in order to simulate the image it provides. Firstly, we simulate the spatial d

We demonstrate that high porosity anodically porous silicon is radioluminescent. Interests of this study are double. Firstly: is the construction of porous silicon X-rays detectors (imagers) possible? Secondly: is it necessary to protect silicon poro

In this paper, we present the experimental validation of the wide signal measurement range of a high sensitivity gateable camera based on a multi step parallel plate avalanche chamber (MSPPAC) for MeV pulsed radiography applications. The MSPPAC was t

We have tested a new concept of segmented scintillating block in order to realize a low cost fast 2D integrating imager for hard x-ray radiography and for neutron radiography. COntrary to other scintillating camera for high energy imaging, our scinti
