Abstract (en)
[origin: WO9921211A1] A radiation detector in which primary electrons are released into a gas by ionizing radiations and drifted through an electric field (E) to a collecting electrode (CE) for detection. It further includes a gas electron multiplier (10, 11, 12) formed by one or several matrices of electric field condensing areas (1i) which are distributed within a solid surface perpendicular to the electric field. Each electric field condensing area consists of a tiny hole passing through the solid surface that forms a dipole adapted to produce a local electric field amplitude enhancement proper to generate an electron avalanche from one primary electron. The gas electron multiplier operates thus as an amplifier or a preamplifier within a host radiation detector.
