Summary:Described are concepts, structures and techniques for passive mitigation of relativistic electrons produced in a tokamak plasma. These electrons may be referred to herein as "runaway" electrons (REs). In embodiments, a passive runaway electron mitigation coil (REMC) comprises an electrical conductor having a non-axisymmetric loop shape comprising a plurality of portions arranged along paths defined by the surface of a torus along a toroidal direction. In operation, the REMC is energized by a disruption-induced voltage, and the resulting magnetic field stochasticity causes electrons to be lost more rapidly than a RE beam can form. The REMC is configured for outboard side mounting within a vacuum vessel.
