“…In contrast, under the conditions of self-focusing of the beam by its own magnetic field, the flow current becomes appreciably turbulent, and the charged particles acquire a significant momentum spread [39]. The electron flow in this case is like a compressed relativistic gas with electron temperature of the order of the voltage applied across the diode [16].…”

“…Though the initially set goal of developing a pellet fusion was not achieved, high-current electron beams found successful applications in other fields of physics [15][16][17]. They are used for research in radiation physics [18], generation of high-power microwaves [19,20], collective acceleration of ions [21,22], and pumping gas lasers [23].…”

A drastic cumulation of current density caused by electrostatic repulsion in relativistic vacuum diodes with ring-type cathodes is described theoretically and confirmed experimentally. The distinctive feature of the suggested cumulation mechanism over the conventional one, which relies on focusing a high-current beam by its own magnetic field, is a very low energy spread of electrons in the region of maximal current density that stems from a laminar flow profile of the charged-particle beam.

Magnetic cumulation is not the sole phenomenon capable to produce high-dense electron beams in relativistic vacuum diodes. Electrostatic cumulation phenomenon also exists and reveals at much lower accelerating voltages in relativistic diodes with a ring-type cathode. A distinctive feature of electrostatic cumulation is quite low spread of electron energies in the produced high-dense beam. These circumstances give advantages to electrostatic cumulation phenomenon if the latter is considered as a convenient research instrument for high energy density physics. Electrostatically cumulated electron beam with energy of 400 keV is capable of exciting a shock wave with an amplitude of 0.25 Mbar in a tungsten plate, which can be used to compress a target. Research can be carried out using one high-current beam or several.

Light ion beam inertial confinement fusion (ICF) is a concept in which intense beams of low atomic number ions would be used to drive ICF targets to ignition and gain. Here, results from numerical simulations are presented describing the operation of an indirect-drive light-ion ICF target designed for a commercial power plant application. The simulations indicate that the ICF target, consisting of an X-ray-driven capsule embedded in a spherical foam-filled hohlraum, will produce a fusion energy output of over 500 MJ when driven with lithium ion beams containing a total input energy of 8 MJ.
