Measurements on plasma focusion 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 E0. The ion number fluence (ions m−2) and energy fluence (J m−2) computed as 2.4−7.8 × 1020 and 2.2−33 × 106, respectively, are found to be independent of E0 from 0.4 to 486 kJ. Typical inductance machines (33–55 nH) produce 1.2−2 × 1015 ions per kJ carrying 1.3%–4% E0 at mean ion energy 50–205 keV, dropping to 0.6 × 1015 ions per kJ carrying 0.7% E0 for the high inductance INTI PF.
