  • Relativistic extension of a charge conservative finite element solver for time dependent maxwell vlasov equations
    Physics of Plasmas, 2018
    Co-Authors: H. Moon, Yuri A Omelchenko, F.l. Teixeira
    Abstract:

    Accurate modeling of Relativistic particle motion is essential for physical predictions in many problems involving vacuum electronic devices, particle accelerators, and Relativistic Plasmas. A local, explicit, and charge-conserving finite-element time-domain (FETD) particle-in-cell (PIC) algorithm for time-dependent (non-Relativistic) Maxwell-Vlasov equations on irregular (unstructured) meshes was recently developed by Moon et al. [Comput. Phys. Commun. 194, 43 (2015); IEEE Trans. Plasma Sci. 44, 1353 (2016)]. Here, we extend this FETD-PIC algorithm to the Relativistic regime by implementing and comparing three Relativistic particle-pushers: (Relativistic) Boris, Vay, and Higuera-Cary. We illustrate the application of the proposed Relativistic FETD-PIC algorithm for the analysis of particle cyclotron motion at Relativistic speeds, harmonic particle oscillation in the Lorentz-boosted frame, and Relativistic Bernstein modes in magnetized charge-neutral (pair) Plasmas.

  • efficient quasi monoenergetic ion beams from laser driven Relativistic Plasmas
    Nature Communications, 2015
    Co-Authors: Sasi Palaniyappan, Christopher E Hamilton, Adam B. Sefkow, D. C. Gautier, Christian Kreuzer, Miguel A. Santiago, R. C. Shah, C. Huang, J C Fernandez
    Abstract:

    Table-top laser-plasma ion accelerators have many potential applications, but achieving simultaneous narrow energy spread and high efficiency remains a challenge. Here, the authors produce ion beams with up to 18 MeV per nucleon whilst keeping the energy spread reduced through a self-organized process.

    Abstract:

    Table-top laser-plasma ion accelerators have many exciting applications, many of which require ion beams with simultaneous narrow energy spread and high conversion efficiency. However, achieving these requirements has been elusive. Here we report the experimental demonstration of laser-driven ion beams with narrow energy spread and energies up to 18 MeV per nucleon and ∼5% conversion efficiency (that is 4 J out of 80-J laser). Using computer simulations we identify a self-organizing scheme that reduces the ion energy spread after the laser exits the plasma through persisting self-generated plasma electric (∼10(12) V m(-1)) and magnetic (∼10(4) T) fields. These results contribute to the development of next generation compact accelerators suitable for many applications such as isochoric heating for ion-fast ignition and producing warm dense matter for basic science.
