Radial Cooling of a Spherical Torus (ST) Toroidal Field (TF) Centerpost
Authors: Robert D. Woolley
Abstract:
It is best for fusion to operate STs at the highest
feasible toroidal field. This may not be obvious since dissipated
electrical power increases as the square of magnetic field
strength. However, fusion power density increases even faster.
For example, increasing TF by 10% increases electrical losses by
21% but it also may increase fusion power by 46.4%.
