Energy Gain of Magnetized Cylindrical D-T Targets in Fast Ignition Fusion
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...

متن کاملFast ignition of fusion targets by laser-driven electrons
We present hybrid PIC simulations of fast electron transport and energy deposition in pre-compressed fusion targets, taking full account of collective magnetic effects and the hydrodynamic response of the background plasma. Results on actual ignition of an imploded fast ignition configuration are shown accounting for the increased beam divergence found in recent experiments [J.S. Green et al., ...
متن کاملIntegrated Simulations of Targets for Fast Ignition with Proton Beams
(0.8 mg of DT at 400 g/cm) has been derived from the energy balance of an hypothetical power plant [2]. Secondly, self-consistent 2D radiation hydrodynamic simulations with MULTI [3, 4] allows us to define and optimize a HIB-driven hohlraum target, as well as to determine the minimum PB energy ( 33 kJ) needed to ignite the asymmetrically compressed fuel. Thermonuclear ignition and burn is now i...
متن کاملVisualizing fast electron energy transport into laser-compressed high-density fast-ignition targets
Recent progress in kilojoule-scale high-intensity lasers has opened up new areas of research in radiography, laboratory astrophysics, high-energy-density physics, and fast-ignition (FI) laser fusion. FI requires e cient heating of pre-compressed high-density fuel by an intense relativistic electron beam produced from laser–matter interaction. Understanding the details of electron beam generatio...
