The small accelerator has been a valuable asset for the development of techniques to assay fissionable materials in support of the Nuclear Safeguards Program. In particular, the availability of a 3-MeV Van de Graaff accelerator as a source of neutrons of precisely controllable energy spectrum, intensity, and time duration has made possible the development of extremely reliable assay systems. Cockroft-Walton-type accelerators of both the conventional and sealed- tube types, used as generators of 14-MeV $sup 3$H(d,n)$sup 4$He neutrons, have also been important in the development of nondestructive assay techniques. Fundamental information obtained from the study of accelerator-based assay systems has also been applied to the development of less expensive, transportable systems which utilize isotopic neutron sources.
