Abstract
The development of high frame rate imaging high energy X-rays detector system is discussed. The purpose of this paper is to highlight some of the issues involved in the development of high performance position sensitive X- and gamma-ray cameras for high frame rate imaging. New CZT technology has provided some prototypes offering more than 50% stopping power (and millimetric spatial resolution) for 5 MeV X-ray pulses. Some different CdTe and CdZnTe sensors were tested with MeV energy photons produced by the accelerators ELSA and ARCO (CEA Bruyeres-le-Chatel). The first experimental results obtained at CEA with 20 ps long are very encouraging for high energy high frame rate imaging applications.
