Self-Generated Magnetic Fields in Laser-Produced Plasmas with 3-D Particle-in-Cell Simulation

Abstract

Electron temperature anisotropy has recently been shown through X-ray spectrum experiments and numerical analyses. It is well known that temperature anisotropy causes many kinds of microscopic instabilities, such as self-generation of magnetic fields. There have been many reports about the observation of strong magnetic fields in ultra-intense lasers. It is important to simulate a plasma system using three-dimensional models and methods in order to investigate many types of temperature anisotropy, three-dimensional structures and nonlinear phenomena related to these large-amplitude magnetic fields. In this work, we will demonstrate 3-D particle-in-cell (PIC) simulation and compare the results with recent data.
