An investigation of many important fusion plasma phenomena, directly affecting the confinement and stability, is only possible through a kinetic modeling because of the underlying effects which have relatively small characteristic scales. Fully kinetic simulations providing all of the information about the particle distribution, however, have a major drawback of their high computational cost.
The usage of a hybrid models is one of the possible ways if one would like to circumvent this limitation and investigate the nature and the physics of the edge transport barrier. By using of a hybrid: a kinetic model for ions and a drift/gyrokinetic for electrons we can resolve all of the effects related to ions without any reduction while still retaining kinetic electron effects.
Basing on the "ssV" code by the computational plasma physics group at Ruhr-Universität Bochum, we are developing a new flux conservative model for the edge tokamak plasma with a flux-aligned coordinates. A delta-f version of code is under development, which is used for the code comparison for the modeling of Landau damping and ITG mode.
