β¦ Synopsis
A bounce-averaged Fokker-Planck code has been developed for studying electron cyclotron heating in tokamak experiments. The equation solved and the numerical scheme used are discussed, and the advantages of the implicit time advancement emphasised. The numerical problems encountered while developing the code are described. The distribution functions predicted by the code are shown to be in good agreement with those produced in experiments.

non-Monte-Carlo path-integral algorithm that is particularly adept in handling nonlinear Fokker-Planck systems is extended to multivariate systems. This algorithm is particularly accurate for systems with moderate noise.

We present the solution of the kinetic equation describing the quasi-linear evolution of the electron momentum distribution function under the influence of the electron cyclotron wave absorption, Coulomb collisions and the dc electric field in a tokamak plasma. The solution of the quasi-linear equat
