PCT No. PCT/FR89/00553 Sec. 371 Date Apr. 26, 1991 Sec. 102(e) Date Apr. 26, 1991 PCT Filed Oct. 24, 1989 PCT Pub. No. WO90/04851 PCT Pub. Date May 3, 1990.The invention relates in particular to a detector for two-dimensional analysis of a flux of photons or neutral particles. The detector comprises a solid plane converter (5) constituted by a two-dimensional matrix of cells (such as 9c), an array of charge-multiplying wires (6) using stimulated ionization of a gas, and a cathode grid (7). The cells both convert the photons or neutral particles and collect the charge, and the ionization is preferably stimulated until self-regulating streams of electrons appear (streamer mode). The invention has application to imaging devices.
