Abstract: A neutron detection device comprises a single gas-filled flat enclosure of constant thickness. A number N X n of identical disintegration ionization chambers are disposed at regular intervals in the enclosure and a cathode and an anode are carried by opposite walls. Responsive to a detection, two electrical pulses are delivered by the two electrodes of a cell and one is addressed to one of the n lines and the other to one of the N columns of a matrix-type network comprising N X n counters each associated by a line and a column of the network with only one of the cells.
