Abstract (en)
[origin: EP0362947A1] Sealed neutron tube containing a deuterium-tritium gas mixture under low pressure from which an ion source furnishes an ionised gas channelled by an electron-confining magnetic field created by magnets (8), the said source emitting ion beams (3) which cross an extraction-acceleration electrode (2) in order to be projected onto a target (4) and produce thereat a fusion reaction causing an emission of neutrons. According to the invention, the ion source is of multi-cellular type consisting of n Penning type cells comprising a multi-aperture anode (6) disposed inside the cathodic cavity (7) so as to increase the ion current. The shape and/or the dimensions and/or the positioning of the multi-aperture anode are adapted to the topology of the magnetic field. <??>Application to neutron generators. <IMAGE>
