Development of a Circularizer for an Endless Mirror Device with l=2 and l=3 Helical Systems

Circularizers in an endless mirror device with l=2 and /=3 helical windings weredesigned using computer calculations of the magnetic surfaces. The parameters deter-mined were substituted into the approximate equations obtained by E. Friman et al.to confirm their adequacy. It was found that the circularizer pitch is two and threetimes larger than that in a helical system of l=2 and /=3, rccspectively; that the circularizer may be mounted anywhere in the mirror part; and that the circularizer cur-rent I. needs about one third that required of helical systems.
