Abstract
The invention relates to a neutral particle detector for providing one-dimensional analysis of a flux (14) of neutral particles which reach it in a sheet. The detector comprises a solid plane converter (17) disposed at a grazing incidence, a grid of charge amplifying wires (18) making use of stimulated ionization of a gas, and charge collecting tracks (19). The tracks are disposed in the immediate proximity of the converter and are subjected to the same electrical potential as the converter. The invention is applicable to imaging.
