TY  - JOUR
AB  - Biermann battery magnetic field generation driven by high power laser–solid interactions is explored in experiments performed with theOMEGA EP laser system. Proton deflectometry captures changes to the strength, spatial profile, and temporal dynamics of the self-generatedmagnetic fields as the target material or laser intensity is varied. Measurements of the magnetic flux during the interaction are used to helpvalidate extended magnetohydrodynamic (MHD) simulations. Results suggest that kinetic effects cause suppression of the Biermann batterymechanism in laser–plasma interactions relevant to both direct and indirect-drive inertial confinement fusion. Experiments also find thatmore magnetic flux is generated as the target atomic number is increased, which is counter to a standard MHD understanding.
