Energy deposition of MeV electrons in compressed targets of fast-ignition inertial confinement fusion
Energy deposition of MeV electrons in dense plasmas, critical for fast ignition in inertial confinement fusion (ICF), is modeled analytically. It is shown that classical stopping and scattering dominate electron transport and energy deposition when the electrons reach the dense plasmas in the cores of compressed targets, while “anomalous” stopping associated with self-generated fields and micro...
متن کاملEnergy 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 کاملRecent Studies in Fast Electron Energy Transport Relevant to Fast Ignition Inertial Fusion
The first results of an experimental campaign are reported in which it is intended to demonstrate whether it is possible for the fast electron beam (produced at irradiances in excess of 1019 Wcm−2μm2) to be artificially collimated even when the beam enters the target with a large divergence angle. The artificial collimation occurs because of a pre-generated magnetic field that is produced by a ...
متن کاملDevelopment of Fast Ignition Integrated Interconnecting Code (FI) for Fast Ignition Scheme
The numerical simulation plays an important role in estimating the feasibility and performance of the fast ignition. There are two key issues in numerical analysis for the fast ignition. One is the controlling the implosion dynamics to form a high density core plasma in non-spherical implosion, and the other is heating core plasma efficiency by the short pulse high intense laser. From initial l...
