“…The acceleration of helium ions is interesting for the excitation of a number of thermonuclear reactions in astrophysics [1][2][3] and in an inertial confinement fusion implosion [4], as well as for the production of short-lived radionuclides for radiopharmaceuticals, especially to produce 18 F via the reactions 16 O( 3 He,p) 18 F (E th ≈ 3.8 MeV) and 16 O(3He,n) 18 Ne (Q > 0) [5,6]. Helium is characterized by the highest single ionization potential, 24.59 eV [7], which reduces the number of its ions in the implementation of collective methods of ion acceleration, for example, by electron rings from the residual atmosphere of the accelerating chamber [8][9][10].…”

The collective acceleration of helium ions from its residual atmosphere in the Luce diode was studied at helium pressures from 0.13 to 0.23 Pa. The energy of accelerated ions was determined from the drift velocity of the virtual cathode accelerating the ions. The number of 4He was determined by radioactivities of 13N and 30P induced in h-BN and Al targets via the nuclear reactions 10B(α,n)13N and 27Al(α,n)30P. The efficiency of capturing 4He ions in collective acceleration from the residual helium atmosphere was estimated as 0.25%. With increasing helium pressure above 0.15 Pa, the energy of the main ion group noticeably decreased to 0.46 MeV/amu compared to the acceleration from a usual residual atmosphere (~0.6 MeV/amu); however, the probability of ion acceleration to a specific energy of up to 1.57 MeV/amu increased significantly. Such increases in the ion energy were accompanied by the appearance of the signal of the second virtual cathode 7–9 ns after the appearance of the first virtual cathode.

“…[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.…”

Interaction of the high energy deuterons with the graphite target in the plasma focus devices based on Lee model

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.

In this work, we use the Lee model to predict the plasma parameters, such as plasma temperature and pinch duration, in the 3.37 kJ DPF device, called “Thailand Plasma Focus-II (TPF-II).” This numerical result is then used to optimize the electrode parameters for the maximum production rate of 18F. The crossing point of pinch duration and pinch temperature is considered to obtain the appropriate electrode length, anode radius and gas gap between anode and cathode. The gas gap between both electrodes is indicated in ratio between cathode radius and anode radius, c. The results show that the best values of c, anode radius and electrode length are 1.48, 1.2 cm and 26.1 cm, respectively, in which the plasma pinch temperature, peak current and pinch duration of 0.76 keV, 207 kA and 8.725 ns can be obtained.
