detectors of radiation and imaging devices comprising such autoradiography

摘要

Radiation detector comprising one or several structure (s) 8 (s) (7) each comprising an input electrode (8) and an output gate (9), which are kept separated by an insulating spacer (11). Each spacer (11) defines the spaces of amplification (22) to generate electrons by the avalanche. The dimensions of these spaces of amplification (22) are decorrelated from those of the meshes of the output gate (9).
