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

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-0. The ion number fluence (ions m(-2)) and energy fluence (J m(-2)) computed as 2.4-7.8 x 10(20) and 2.2-33 x 10(6), respectively, are found to be independent of E-0 from 0.4 to 486 kJ. Typical inductance machines (33-55 nH) produce 1.2-2 x 10(15) ions per kJ carrying 1.3%-4% E-0 at mean ion energy 50-205 keV, dropping to 0.6 x 10(15) ions per kJ carrying 0.7% E-0 for the high inductance INTI PF.
