Kinetic modeling of fast electron dynamics and self-consistent magnetic fields in a reversed-field pinch
The dynamics of fast electrons in a reversed field pinch configuration is investigated by numerically solving the appropriate kinetic equation in 3 dimensions (2 dimensions in velocity space and 1 dimension in real space). A Fokker-Planck code has been developed, including Coulomb collisions, dc electric field, radial diffusion due to magnetic turbulence, ambipolar electric fields, and the self-consistent evaluation of the magnetic fields generated by the plasma itself. This has allowed the kinetic dynamo model to be validated theoretically in a realistic geometry. The main parameters of standard discharges in the largest existing facility of this RFX type have been simulated successfully.
