“…Te concept of IEC was frst suggested to try to solve the problem of controlled fusion by Lavrent'ev in 1950 (see [22][23][24][25]28] and refs therein). Te frst theoretical paper on IEC appeared only in 1959 and was devoted to the IEC with reverse polarity [21].…”

“…At the same time, another approach like plasma confnement under extreme conditions in a single device for pB fusion without any external infuences is also still of great interest [20]. Overall, the inertial electrostatic confnement (IEC) [21][22][23][24][25][26][27][28] is one of the very few in which ions can quite easily reach the energies required for the beginning of the pB reaction.…”

Oscillating Plasmas for Proton- Boron Fusion in Miniature Vacuum Discharge

Earlier, the experiments on the aneutronic proton-boron (pB) fusion in a miniature nanosecond vacuum discharge (NVD) with oscillatory plasma confinement and correspondent α particles yield were presented. In this work, we consider some specific features of oscillatory confinement as a relatively new type of plasma confinement for fusion. Particle-in-cell (PiC) simulations of pB fusion processes have shown that the plasma in NVD, and especially on the discharge axis, is in a state close to a quasineutral one, which is rather different from the conditions in the well-known scheme of periodically oscillating plasma spheres (POPSs) suggested earlier for fusion. Apparently, small-scale oscillations in NVD are a mechanism of resonant ion heating, unlike coherent compressions in the original POPS scheme. Nevertheless, the favorable scaling of the fusion power in NVD turns out to be close to the POPS fusion but differs significantly both in the compression ratio and in the values of the parameter of quasineutrality. In addition, unlike the POPS scheme, PiC simulation reveals that the distribution functions of protons and boron ions in NVD are non-Maxwellian. Therefore, we have an aneutronic pB synthesis in a nonequilibrium plasma remaining “nonignited” on the discharge axis.

“…Inertial electrostatic confinement (IEC) is a technique for producing nuclear fusion in small-scale devices originally proposed by Lavrent'ev [1,2] and further developed by Hirsch [3,4] and Farnsworth [5,6]. In this method, the concentric spherical or cylindrical electrodes are used to trap and heat ions to fusion relevant energies.…”

“…Inertial effects associated with dynamic motion of the confined species are essential to avoid plasma losses predicted for systems by Earnshaw [3]. Credit for its invention is independently given to U. S. scientist Philo Farnsworth and Russian scientist Oleg Lavrent yev, as both formulated means of electrostatic confinement almost simultaneously throughout the 1950 and into the 1960 [4,5,6,7].…”

Abstract:The aim of this paper introduces the preliminary results of the design and construction of first Egyptian inertial electrostatic confinement IEC fusion device. It consists of 2.8 cm stainless steel cathode, 6.5 cm anode diameter with 10 cm diameter 30 cm height vacuum chamber. The operation of IEC experiments has concentrated on pulsed operation to achieve the high currents required to generate increased reactions rates. The discharge voltage waveform with peak voltage 20kV with a full width half maximum (FWHM) of 10 nanoseconds and current pulse waveform has been registered using pick-up coil with peak current about 150mA. Experiments are performed with air as operating gas at different pressures and voltages. Time resolved of x-ray radiation signals are obtained using fast radiation detector.
