Description

HiPACE is a relativistic, fully electromagnetic, three-dimensional (3D) and MPI-parallelized particle-in-cell (PIC) code. It uses the quasi-static approximation to efficiently model particle-beam driven plasma-wakefield accelerators. HiPACE exploits the disparity of time scales in the interaction of highly relativistic particle beams with plasma to decouple beam and plasma evolution. This enables time steps which can be many times greater than those used in standard finite-difference time-domain PIC codes that simulate the interaction in the laboratory frame, and therefore renders possible a reduction of the required number of core-hours by orders of magnitude.

The current version of HiPACE computes all electromagnetic field components and allows for the fully consistent simulation of non-cylindrically-symmetric phenomena, such as the hose instability.

In 2021, a rewrite in C++, supporting modern GPUs and new algorithms was published as HiPACE++.
