“…Recent reviews [8][9][10][11] suggest imminent emergence of DPF as a technology platform for commercially significant applications. At the same time, there is also some revival of interest in DPF as a device for generating fusion energy [12] and other nuclear reactions [13]. Device optimization issues are very different in the two cases.…”

“…The idea that this is caused by a linear beam of ions accelerated by induced axial electric field generated by instabilities or anomalous resistance is belied by evidence of accelerated ions in both forward and reverse axial directions as well as by evidence showing radially directed motion [4]. Clearly, an analytic theory, however approximate, which gives a global picture of dependencies between control parameters and properties of the accelerated ion population, would be very valuable for plotting the road map for the quest for aneutronic fusion energy [12] and other nuclear reactions [13].…”

“…The study of the dynamics of the plasma focus covered the formation and acceleration of the plasma layer inside the device [3] and the factors affecting such as the sheath current [4], pinch current [5], length of the insulator used to separate the anode and the cathode, the type of gas used within the device [6,7], the parameters of the capacitor bank [8] and electrode engineering, and ion beam properties produced in dense plasma focus devices using various gases [9]. Due to the collapse of the plasma pinch after a short period of time (several ns) of its formation and emitting ions and electrons in opposite directions, many studies have been conducted that dealt with the possibility of benefiting from the emitted particle beams such as lithography [10,11] and short-lived radioisotope produc-tion [12][13][14][15] thin film deposition [16,17]. The soft X-ray emission from dense plasma focus is according to two mechanisms: linear radiation and continuum radiation (recombination and Bremsstrahlung radiation) [18][19][20].…”

“…[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.…”
