Abstract
The orbit loss current is calculated for the ASDEX Upgrade geometry us ing the 5D (3D in configuration space and 2D in velocity space) Monte Carlo code ASCOT. The balance between the obtained current and the ana lytical estimate of the return current shows an GH transition for the normalized collision frequency nu(i) approximate to 1 as expected fro m analytic theory. The transition in ASDEX Upgrade, however, occurs at larger Values of nu(i).
