Generation of Collimated MeV γ-rays from Intense Poincaré Beam-Plasma Interaction
POSTER
Abstract
The production of a petawatt γ-ray beam is demonstrated using a novel configuration based on fully-structured light irradiating a dense plasma. We study how the relativistic pulse efficiently confines and accelerates plasma electrons, driving a quasi-static field that stimulates magneto-bremsstrahlung radiation. The emitted γ-rays are highly collimated and account for upwards of 20% of the incident field energy. The essential characteristics of the interaction are validated using three-dimensional particle-in-cell simulations.
