Global drift wave map equations that allow the integration of particle orbits on long time
scales are implemented to describe transport. Ensembles of test particles are tracked to
simulate the low-confinement mode/reversed shear/enhanced reversed shear plasmas in
the Tokamak Fusion Test Reactor (TFTR) tokamak and the Optimized Shear plasma in the
Joint European Torus (JET) tokamak. The simulations incorporate a radial electric field, Ē r,
obtained from a neoclassical calculation [Zhu et al., Phys. Plasmas 6, 2503 (1999)] and a …

Global drift wave map equations allow the integration of particle orbits on the long time scale
needed to describe transport. Ensembles of test particles are used to simulate the L-
mode/RS/ERS plasmas in TFTR, and the pellet injected OS plasma in JET. For the
simulation, we adopt the result from neoclassical calculation of the radial electric field E r
and the Taylor et al. model for the drift wave fluctuations which takes into account the
change of mode structures by E_r. The simulations give steady state particle density profile …
