    Control of Electron Beam Using Strong Magnetic Field for Efficient Core Heating in Fast Ignition

    Full text link
    For enhancing the core heating efficiency in electron-driven fast ignition, we proposed the fast electron beam guiding using externally applied longitudinal magnetic fields. Based on the PIC simulations for the FIREX-class experiments, we demonstrated the sufficient beam guiding performance in the collisional dense plasma by kT-class external magnetic fields for the case with moderate mirror ratio (~<10 ). Boring of the mirror field was found through the formation of magnetic pipe structure due to the resistive effects, which indicates a possibility of beam guiding in high mirror field for higher laser intensity and/or longer pulse duration.Comment: 11pages, 8figure

    Collimated electron jets by intense laser beam-plasma surface interaction under oblique incidence

    Get PDF
    Oblique incidence of a p-polarized laser beam on a fully ionized plasma with a low density plasma corona is investigated numerically by Particle-In-Cell and Vlasov simulations in two dimensions. Energetic electrons which propagate into the plasma corona in front of the target are observed. The fast electrons are collimated by quasi-steady magnetic fields. The magnetic fields enhance the penetration depth of the electrons into the corona. A scaling law for the angle of the ejected electrons with incident laser intensity is given
