Abstract

Fast particles are created in many scenarios where RF-waves are used for heating and current drive in fusion plasmas. Furthermore, they can interact with fusion born alpha particles. Consequently, it is important to have a capability to model the interaction between RF-waves and fast ions. Moreover, in order to carry out detailed predictive simulations, the modelling must integrate several codes. In order to address this problem, the orbit following Monte Carlo code SPOT has been developed and integrated into to the transport code CRONOS. Newly derived Monte Carlo operators account for the interaction of RF-waves and ions in SPOT. As a first application, the interaction between alpha particles and Lower Hybrid waves has been studied. This has necessitated a self-consistent coupling of SPOT with the LH ray-tracing/Fokker-Planck (for the electrons) code DELPHINE.
