Abstract
We performed an experiment aiming to demonstrate the collimation of fast electrons by the magnetic field generated at the resistivity gradient in imploded plasma. By using a solid sphere target with an inserted high-Z metal wire, the number of fast electrons reaching the imploded core increased by 93%. The generation of the magnetic field and collimation of fast electrons are confirmed by a two-dimensional Particle-in-Cell simulation using plasma parameters calculated by a radiative hydrodynamic simulation.
期刊介绍：
High Energy Density Physics is an international journal covering original experimental and related theoretical work studying the physics of matter and radiation under extreme conditions. ''High energy density'' is understood to be an energy density exceeding about 1011 J/m3. The editors and the publisher are committed to provide this fast-growing community with a dedicated high quality channel to distribute their original findings.
Papers suitable for publication in this journal cover topics in both the warm and hot dense matter regimes, such as laboratory studies relevant to non-LTE kinetics at extreme conditions, planetary interiors, astrophysical phenomena, inertial fusion and includes studies of, for example, material properties and both stable and unstable hydrodynamics. Developments in associated theoretical areas, for example the modelling of strongly coupled, partially degenerate and relativistic plasmas, are also covered.
