Magnetic field amplification and radiation emission in relativistic beam-plasma systems
Abstract/Contents
- Abstract
- Magnetic field amplification by relativistic plasma instabilities is crucial to many beam-plasma systems. In high-energy astrophysical environments, these instabilities can mediate collisionless shock formation, particle acceleration, and radiation emission, while in the laboratory they can affect laser-matter interaction related to compact radiation sources and inertial fusion. In this Thesis, we report the discovery of a new nonlinear plasma streaming instability which generates much stronger, larger-scale magnetic fields than previously thought possible in dilute, relativistic beam-plasma systems. Our kinetic theory for the growth and saturation of this instability is validated in plasmas of varying composition by multidimensional particle-in-cell simulations and indicates that it could lead to significantly enhanced particle acceleration in gamma-ray bursts. We further show that modern high-power laser and accelerator facilities can drive lepton beams large enough to probe multiple relativistic instabilities. We derive requirements on the lepton beam characteristics needed to study these instabilities in astrophysically-relevant laboratory conditions and show that they can enable unprecedented x-ray flux needed for high energy density science experiments.
