We present a new ion kinetic model describing the ignition and burn of the deuterium-tritium fuel of inertial fusion targets. The analysis of the underlying physical model enables us to develop efficient numerical methods to simulate the creation, transport and collisional relaxation of fusion reaction products (α-particles) at a kinetic level. A two-energy-scale approach provides a framework f...

Inertial Electrostatic Confinement (IEC) plasma systems were investigated experimentally at the University of Kentucky with air and argon as working gas at pressure levels between 10 and 100 mTorr and at electrical powers up to 60 W clearly aiming at nonfusion IEC operation. Starting from conventional spherical grid configurations, a cylindrical system with helix shaped electrodes was developed...

The problem of standing wave formation by superposing two counter-propagating whistler waves in an overdense plasma, studied recently Sano et al. (Phys. Rev. E 100, 053205 (2019) and Phys. 101, 013206 (2020)), has been revisited the relativistic limit. A detailed theory along with simulation performed to study interaction counter propagating relativistically intense waves. explains such process...

In recent years, many different plans have been considered to use the nuclear energy gained from inertial confinement fusion (ICF) as attempts to obtain high energy efficiencies. In conventional ICF methods, a small amount (about mg) of the deuterium–tritium compound is confined in a small spherical chamber of a few millimeters in radius and compressed by laser or heavy ion beams with powers in...

A novel plasma confinement concept based on plasma confinement by electromagnetic pressure of circularly polarized electromagnetic fields is proposed. Practical implementation of this concept in a toroidal device is suggested. In this concept the confining field frequency is in the lower range such that the size of the device is much smaller than the vacuum wavelength. Most of the previous radi...

We present first results from a novel experimental platform that is able to access physics relevant topics including indirect-drive magnetized inertial confinement fusion, laser energy deposition, various in atomic physics, and laboratory astrophysics (for example, the penetration of B-fields into high density plasmas). This uses x rays wire array Z-pinch irradiate silicon target, producing an ...

This paper presents a scheme for strong self-focusing of laser beam interacting with cone-guided fast-ignition inertial confinement fusion target using cone pre-plasma filling as an optical medium reducing the waist. The objective is to reduce focal spot size at interior tip re-entrant that required efficient coupling dense imploded fuel core. challenging achieve in large system standard compon...
