METHOD AND DEVICE FOR THE BIDIMENSIONAL LOCALIZATION OF NEUTRAL PARTICLES, PARTICULARLY FOR LOW COUNTING RATIOS

摘要

The invention relates particularly to a detector allowing to carry out a bidimensional analysis of a neutral particle flow. Said detector is comprised of a solid planar converter (5) including a bidimensional array of cells (such as 9c), a network of charge multiplication wires (6) using the stimulated ionization of a gas, and a cathode grid (7). The cells provide for both the conversion of neutral particles and the collecting of charges, the ionization being preferably stimulated till the occurrence of self-regulated trails of electrons (streamer mode). Application to imaging.
