Plasma Focus Device as a Breeder of Proton to Produce Short Lived Radioisotope 18F
Tóm tắt
In a plasma focus device, the nuclear fusion products are created through the thermal and non-thermal (beam-target) mechanisms. The beam target character of the pinched plasma is used to determine the yield of 3.02 Mev protons (when deuterium filling gas is used) at the optimized regime. For this situation, a combination of “moving boiler” model and a shock wave theory are employed. The numerical simulations for the production of the positron emitter nuclide, 18F (T
1/2 = 110 min; widely used in positron emission tomography), for two Mather type devices (NX2 and PF1000) show that, the rules of the drift velocity as well as the drive parameters have an high impact on the final yields.
