Simulation of bootstrap current in 2D and 3D ideal magnetic fields in tokamaks

Olivier Sauter, Jonathan Graves, Wilfred Anthony Cooper, Madhusudan Raghunathan, Michael Pedro

We aim to simulate the bootstrap current for a MAST-like spherical tokamak using two approaches for magnetic equilibria including externally caused 3D effects such as resonant magnetic perturbations (RMPs), the effect of toroidal ripple, and intrinsic 3D e ...
