Application of the Berkeley Lab Accelerator Simulation Toolkit to the Modeling of Plasma Accelerator Experiments

30/7-018 - Kjell Johnsen Auditorium (CERN)

The Berkeley Lab Accelerator Simulation Toolkit (http://blast.lbl.gov) contains a collection of state-of-the-art simulation codes for the modeling of conventional accelerators and plasma-based accelerators. The Warp framework enables 2-D planar and 3-D simulations of plasma-based accelerators using an optimal Lorentz boosted frame to reduce computational time. It can also perform axisymmetric simulations (with azimuthal Fourier decomposition) in the frame of the laboratory. The code FBPIC employs a spectral Fourier-Bessel representation to extend the applicability of axisymmetric simulations with azimuthal Fourier decomposition to Lorentz boosted frame simulations. The BLAST toolkit, Warp and FBPIC will be presented, with examples of applications. A new code that is in development, named WarpX, will also be presented. WarpX, developed within the U.S. DOE Exascale project implements optimized versions of the Particle-In-Cell kernel via the PICSAR library, and Adaptive Mesh Refinement (AMR) via the AMReX library. Initial example applications of PICSAR will be presented.
