torus
An object formed by joining the two ends of a cylinder producing a doughnut shape with a circular cross-section.

A magnetic field inside the orbit is always twice as strong as the magnetic field on the orbit, the radius of the orbit remains constant, so that the acceleration chamber can be made in the shape of a torus, or doughnut.

The poles of the magnet are tapered to cause the field near the orbit to weaken with increasing radius.
