Transformer design for toroidal discharge systems

The transformer requirements for experiments on toroidal discharge systems are rather unusual. The basic problem, as it can be presented to the transformer designer, is described. The design of iron-cored and air-cored transformers is discussed, and it is shown that the transformer problem is not one which can be considered apart from the associated equipment. Such factors as the effect of the transformer design on energy storage requirements and torus dimensions must be taken into account. An arrangement is discussed in which the transformer is also the energy store, magnetic energy being switched between primary and secondary.
