“…Many authors reported strong anisotropy of high-energy deuterons (ratio of axial to radial deuterons in the range 10 2 -10 4 ), when deuterium was used as the filling gas. This anisotropy increases with deuteron intensity (Gullickson and Sahlin, 1978;Antanasijević et al, 1997;Szydlowski, 2003). The established deuteron anisotropy and deuteron energy spectra (energies up to 1.5 MeV) are directly correlated to the neutron yield (Springham et al, 2000) and also with the angular distribution of emitted neutrons which shows a double structure (Castillo et al, 2003).…”

“…On the basis of the performed experiments with the deuterium as working gas, we obtained results: angular distributions of the 4 He and soft X-ray (~5 keV) emitted in described experimental conditions are nearly isotropic. Distribution of emitted deuterons has the maximum in the direction of central electrode [13]. In the deuterium plasma focus 4 He are produced in the several points above central electrode (hot spots).…”

The plasma focus experiment in Belgrade, Serbia started in the late eighties of the last century. The historical overview of the research activity on the Belgrade plasma focus device (BPFD) will be presented in this work. The special attention has been made to the present status and the future plans for the fundamental and applied research as a part of the project of the studies of rare nuclear and particle processes in nature. BPFD is intended to operate as optimized neutron source or hard X-ray source. Using Lee model code as a reference, several upgrades of BPFD must be made: better shielding against EMI pulse, rearrangement of capacitors bank so that higher repetition rate can be achieved and also faster digital acquisition system. BPFD can be used for neutron activation or production of short-living radioisotopes. These radioisotopes will have very low activity which can be analyzed in the underground Low-Background Laboratory for Nuclear Physics, Zemun. Also, we compared the obtained experimental data (neutron yield, total current waveform, working gas pressure) with the numerical simulation code (The Lee model code) to test our plasma focus machine. Comparison between neutron yield from our experimental data and neutron scaling laws and neutron yields derived from computation using the Lee Model code shows good matching, but for better verification of the code, more experimental data are needed.
