Fast Neutron Generator 14 MeV (IGN-14)

The fast neutron generator IGN-14 is a neutron source device which contains a compact linear accelerator and produces neutrons by fusing isotopes of hydrogen. The fusion reactions take place in the device by accelerating either deuterium onto a metal target which contain tritium (T/Ti) or …. (?).
