Abstract
A sealed neutron tube is set forth which contains a low-pressure gaseous deuterium-tritium mixture wherefrom an ion source forms an ionized gas which is guided by a magnetic electron confinement field produced by magnets (8), which source emits the ion beams (3) which traversed an extraction-acceleration electrode (2) and which are projected onto a target (4) so as to produce therein a fusion reaction which causes an emission of electrons. In accordance with the invention, the ion source is of a multi-cell type formed by n Penning-type cells comprising a multi-hole anode (6) which is arranged inside the cathode cavity (7) in order to increase the ion current. The shape and/or the dimensions and/or the position of the multi-hole anode are adapted to the topology of the magnetic field.
