Abstract
It is pointed out that the optimum current density distribution for stress-limited, high-field, high-power magnets can be approached by magnets built up of many thin coils, to maximize their efficiency (`tesla per watt´). By optimizing the radial thickness and height of each subcoil, magnets consisting of only 8 Bitter coils can closely approximate the optimum. For instance with 24 MW such a magnet of inner and outer radii of 28 mm and 420 mm, respectively, could generate over 30 T. The authors therefore propose a new method of magnet construction, the Poly-Bitter magnet
