An analysis has been performed of the INEL Intense Slow Positron Source (ISPS) concept. The results of the theoretical study are encouraging. A full-scale device with a monoenergetic 5 KeV positron beam of {ge}10{sup 12} e{sup +}/s on a {le}0.03-cmdiameter target appears feasible and can be obtained within the existing infrastructure of INEL reactor facilities. A 30.0-cm-diameter, large area source dish, moderated at first with thin crystalline W films and later by solid Ne, is proposed as the initial device in order to explore problems with a facility scale system. A demonstration scale beam at {ge}10{sup 10} slow e{sup +}/s is proposed using a {sup 58}Co source plated on a 6-cm-diameter source dish insert, placed in a 30- cm adapter.
