“…The special attention was made to the profile of the axial protons emitted from the hydrogen plasma focus [18]. Unfortunately, the obtained experimental results show that it is not possible to realized 7 Li(p, α)α fusion reaction in a small plasma focus device (stored energy of 5.76 kJ) [19].…”

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.

“…Activity of the short-living radioisotope was to 1 µCi per discharge [6]. Importance of the shortliving radioisotopes' production is pointed out because of the possible use of the plasma focus device as an alternative to cyclotrons in positron emission tomography (PET) [7,8].…”

“…[1][2][3][4][5] Plasma focus devices have been widely used, in the past for manifold applications like x-rays and electron beams lithography, 6 radiography of biological specimens, 7 and as a rich ion source for various material science applications. [8][9][10][11][12][13][14][15][16][17] We consider the use of plasma focus devices with sufficient ion energy to produce a number of short lived radioisotopes (SLR) such as 13 N, 17 F, 18 F, 15 O, and 11 C through either external solid (exogenous method) [18][19][20][21][22][23][24][25][26][27][28][29][30] or high atomic number gas (endogenous method) [31][32][33][34][35][36][37][38][39][40][41][42] targets. These short lived radioisotopes are positron emitter used for positron emission tomography (PET) imaging.…”

Numerical experiments are systematically carried out using the Lee model code extended to compute the ion beams on various plasma focus devices operated with Deuterium gas. The deuteron beam properties of the plasma focus are studied for low and high energy plasma focus device. The energy spectral distribution for deuteron ions ejected from the pinch plasma is calculated and the ion numbers with energy around 1 MeV is then determined. The deuteron-graphite target interaction is studied for different conditions. The yield of the reaction 12 C(d,n) 13 N and the induced radioactivity for one and multi shots plasma focus devices in the graphite solid target is investigated. Our results present the optimized high energy repetitive plasma focus devices as an alternative to accelerators for the production of 13 N short lived radioisotopes. However, technical challenges await solutions on two fronts: (a) operation of plasma focus machines at high rep rates for a sufficient period of time (b) design of durable targets that can take the thermal load.
