The Drift Kinetic Equation Solver (DKES)[1] solves a set of 3D drift kinetic equations to obtain upper and lower bounds for the diffusion coefficients of a prescribed toroidal plasma equilibrium. The three dimensions are theta (poloidal angle), zeta (toroidal angle), and alpha (pitch angle). Straight-line flux coordinates are used to describe the equilibrium, which must satisfy the stellarator symmetry conditions.
