“…the ion beam component with E z 12 MeV has a low intensity, which cannot be detected with our Faraday cup). We note that there is also no appreciable signal from the Faraday cup as a * For E + AE < 0.3 MeV, our Thomson spectrometer data indicate that t(E + AE) > t(E) [4]. Consistently, the ion energy E = 0.3 MeV is also the limit below which our new TOF method is not applicable.…”

The energy spectrum of the deuteron beam along the electrode axis (0 degrees ) in a plasma focus discharge has been determined with a time of flight (TOF) method and with a differential filter method in the ion energy interval E=0.3-9 MeV. The ion TOF method is applied to single-ion pulse events with an ion emission time t(E) that is only weakly dependent on the ion energy E for E>0.3 MeV. The correlation of the ion beam intensity with the filling pressure, the neutron yield and the hard X-ray intensity is also reported

Production of radioisotopes within a plasma focus device

et al. 2005

In recent years, research conducted in the US and in Italy has demonstrated production of radioisotopes in plasma focus devices, and particularly, on what could be termed "endogenous" production, to wit, production within the plasma it self, as opposed to irradiation of tar gets. This technique relies on the formation of localized small plasma zones characterized by very high densities and fairly high temperatures. The conditions prevailing in these zones lead to high nuclear reaction rates, as pointed out in previous work by several authors. Further investigation of the cross sections involved has proven necessary to model the phenomena involved. In this paper, the present status of research in this field is re viewed, both with regards to cross section models and to experimental production of radio isotopes. Possible out comes and further development are discussed

“…The most credited picture of the phenomena taking place within the focus for the production of SLRs suggests that small (20-300 mm) localized plasma zones, called plasmoids, lasting from 0.5 to 5 ns, will form within the pinch volume, showing very high densities (above solid), fairly hot temperatures (above 3 keV), and magnetic fields sufficiently strong to trap ions with energies of the order of 5 MeV. Such density and temperature conditions are conducive to high nuclear reaction rates [6][7][8][9]. Those high reaction rates are the key to the so-called Endogenous production, in which SLRs are bred within the plasma [4,5].…”
