Plasma Focus Device as a Breeder of 14.66 MeV Protons to Produce Short-Lived Radioisotopes
Journal of Fusion Energy
In plasma focus devices filled deuterium gas with low pressure admixture gas, 3He, the deuterium creates high energy protons of 14.66 MeV through the 3He(d, p) 4He(Q = 18.35 MeV) fusion reaction. This reaction takes place due to the thermal and non-thermal (beam-target) mechanisms. The proton yield production for deuterium filling gas is determined by using the beam-target character of the pinched plasma and moving boiler model. If we use a low pressure admixture gas like 11B, these high energy protons in turn, could generate short-lived radioisotopes like 11C (used in positron emission tomography) via the 11B(p, n)11C reaction. Calculations indicate the influence of drive parameter to the final yield for a Mather type device.
