Abstract

The conservation of the momentum during particle collisions is important for studying the electron cyclotron current drive (ECCD). Two momentum conserving collision models are considered applying an iterative method and implemented to GNET code, in which the drift kinetic equation for energetic electrons are solved in 5-D phase space. The simulation results show a good conservation of the momentum and the calculated ECCD current is larger than the non-conserving one.
