Mike,

The forces are in a cylindrical coordinate system (r,theta,z) about the center of the machine, so the toroidal direction is 'theta' and also happens to be in the plane of the coils. That also puts radial and vertical in the stellarator cross section plane.

toroidal is in the plane of the coil?
are radial and vertical in the plane of the coil or in the stellarator cross section plane?
