Title: Plasma focus ion beam fluence and flux-Scaling with stored energy

Abstract

Measurements on plasma focus ion beams include various advanced techniques producing a variety of data which has yet to produce benchmark numbers [A Bernard et al., J. Mosc. Phys. Soc. 8, 93-170 (1998)]. This present paper uses the Lee Model code [S Lee, http://www.plasmafocus.net (2012)], integrated with experimental measurements to provide the basis for reference numbers and the scaling of deuteron beams versus stored energy E{sub 0}. The ion number fluence (ions m{sup -2}) and energy fluence (J m{sup -2}) computed as 2.4-7.8 Multiplication-Sign 10{sup 20} and 2.2-33 Multiplication-Sign 10{sup 6}, respectively, are found to be independent of E{sub 0} from 0.4 to 486 kJ. Typical inductance machines (33-55 nH) produce 1.2-2 Multiplication-Sign 10{sup 15} ions per kJ carrying 1.3%-4% E{sub 0} at mean ion energy 50-205 keV, dropping to 0.6 Multiplication-Sign 10{sup 15} ions per kJ carrying 0.7% E{sub 0} for the high inductance INTI PF.
