The Pulselac Program at Sandia Laboratories is a recent addition to the Heavy Ion Fusion Program. The purpose of this paper is to give a brief introduction to the work performed to date and future plans for the development of high current accelerators. The basis of the program is the investigation of practical methods of neutralizing the space charge of intense ion beams both in accelerating and transport regions. Alleviation of space charge constraints on ion beam transport would open up a broad range of new options for accelerator fusion drivers. The method to be employed is the introduction of electrons from external sources into the volume of the ion beam, allowing the relaxation towards a state of lower potential energy. Both the spatial location and velocity distribution of the electrons must be controlled. Our approach is to utilize weak magnetic fields, which have negligible effect on the ion orbits, to accomplish this. The program has two major goals. The first is to gain an understanding of the general phenomenon of beam neutralization. The second is to demonstrate the technological feasibility of the utilization of these principles to produce multi-kiloampere ion beams in a controlled and reproducible manner.
