The availability of compact, relatively inexpensive cyclotrons offers an attractive alternative to the commonly used 14 MeV neutron generator for the production of high fluxes of fast neutrons. The high extracted beam current of energetic charged particles from the cyclotron can be used with a variety of solid and gaseous targets to produce neutrons with energies from thermal to 40 MeV with source strengths greater than 10 to the twelfth n/sec. The forward directed distribution of neutron flux and the possibility of removing the neutron producing targets from the cyclotron also offer unique possibilities for the collimation and motion of the neutron beam with respect to a fixed irradiation area.
