“…[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.

“…At this instant a filament of hot and dense plasma (pinch) is formed in front of the inner electrode (usually the anode). After a very short time due to instabilities the plasma column breaks up and decays [19]. Details of the time scale and other plasma parameters will be given later.…”

UIPFF1 is a new Filippov-type plasma focus facility, constructed and built in Esfahan University. This paper reports on the design of the UIPFF1. The main stages of the construction, design and the preliminary X-ray detection tests on the UIPFF1 are mentioned concisely. Measurement results show that in a typical discharge experiment, the discharge current =181 kA, period of current signal = 7.9 µs, the total inductance of the device =132 nH and electrical resistance of the circuit = 77 mΩ. The calibration factor is measured as 121 kA/V by averaging from data obtained with a set of 5 experiments. Temporal changes in plasma focus discharge current, confirmed occurrence pinch at a specific pressure of argon, neon and nitrogen gases.
