Abstract
The invention relates to the examination of samples which, by thermal or photon excitation, are able to emit electrons. These electrons are detected and located by a counter incorporating a cathode forming a mesh network. Pointed anodes coincide with the axes of the meshes. The enclosure of the apparatus is sealed by the sample and its excitation means. The invention can be used in dosimetry or in the checking of surface states.
