Full-orbit Studies of Alfven Eigenmode Induced Fast-ion Losses in DIII-D

In recent experiments at DIII-D, cases of a significant discrepancy between measured and predicted fast-ion pressure profiles have been documented. In the region of enhanced fast-ion diffusion strong Alfv\`enic activity was observed. In this paper we present results of full-orbit simulations of fast-ion transport and investigate to what extend the finite Lamor radius influences fast-ion transport. The simulations are done with the SPIRAL code and include the full magnetic and electrical field fluctuation contributions from the AEs.
