Abstract
Solution of the 2D relativistic quasilinear Fokker-Planck equation is highly desirable in problems of numerical simulation of RF current drive in tokamak plasmas, especially in codes coupling ray-tracing and transport. For practicality, a fast Fokker-Planck solver is needed. We present in this work a fast 2D Fokker-Planck solver which can be applied for time dependent current drive problems. The code is 2D relativistic, and includes the complete first Legendre harmonic term for electron-elect...

Nature of problem
We present in this work a fast solver for the linearized 2-D relativistic Fokker-Planck equation for current drive problems. The code makes use of the accurate relativistic collision operators presented in Ref. [14]. Convergence to the steady state can be reached in about 30 iterations. Very good precision for the solution of the distribution function can be obtained for high relativistic velocities. In the case of fast wave current drive problems, the damping of the wave is calculated self-cons ...
