3-D Fokker-Planck code valid for arbitrary collisionality and adjoint function for bootstrap current calculationFunded under: FP3-FUSION 11C
A 3-D code, CQL(parallel), has been developed, which solves the drift-kinetic Fokker-Planck equation along the magnetic field line on a given flux surface. It is 2-D in velocity space and 1-D spatially along B. No bounce-averaging is performed and the model is valid for arbitrary collisionality and axisymmetric tokamak equilibria. The adjoint function formalism has been adapted to calculate the neoclassical bootstrap current, assuming small banana width compared with the minor radius. The results of the code are compared with published analytical formulae and with the results of the modified bounce-averaged code CQL3D.
