<unk> s are<unk>  source devices which contain compact linear accelerators and that produce<unk> s by fusing isotopes of hydrogen together.  The fusion reactions take place in these devices by accelerating either deuterium, tritium, or a mixture of these two isotopes into a metal hydride target which also contains either deuterium, tritium or a mixture.  Fusion of deuterium atoms (D + D) results in the formation of a He-3 ion and a<unk>  with a kinetic energy of approximately 2.5 MeV.  Fusion of a deuterium and a tritium atom (D + T) results in the formation of a He-4 ion and a<unk>  with a kinetic energy of approximately 14.1 MeV.
Thousands of such small, relatively inexpensive systems have been built over the past five decades.
