Abstract

A new GPU-accelerated hybrid code is presented for the analysis of energetic-particle-driven modes and transport and losses of particles. Its acceleration capabilities and excellent scaling of GPU partitions allow for integration of a large number of numerical particles, making it possible to simulate the full-orbit and full-F dynamics of the energetic particle population. The standard ITPA and the NLED AUG benchmarks are presented and the code is applied for the first time to a recent DT JET discharge, providing insight into the linear excitation and nonlinear saturation of the observed modes in the presence of realistic distribution functions.
