Warp PBA

• Warp PBA is a Sirepo-based prototype for simulating beam-driven and laser-driven plasma wakes, with close-to-cylindrical symmetry.

• Warp PBA supports a small subset of Warp’s capabilities.

• A 2D cylindrical mesh is used for electromagnetic PIC, together with an arbitrary number of azimuthal modes to capture non-cylindrical dynamics. Only one azimuthal mode is required to model a linearly-polarized laser pulse.

• The underlying physics kernel is based on Warp, a massively parallel PIC code.

• The Warp source code is available on Bitbucket.

• The code is primarily supported by David Grote, Jean-Luc Vay, Remi Lehe and other colleagues at Lawrence Berkeley National Laboratory and Lawrence Livermore National Laboratory. Warp is part of the Berkeley Lab Accelerator Simulation Toolkit.
