Accelerating particles in the microtron by non-sinusoidal field
Abstract
A theory for accelerating particles in a microtron by means of an RF field with nonsinusoidal time variation is presented, and an experiment with a 7 MeV microtron is described. It is shown theoretically that the phase acceptance of a microtron can be considerably increased if the accelerating RF field is composed of a fundamental frequency and one of its higher harmonics. The possible increase in power efficiency is nevertheless moderate due to higher cavity losses and to the fact that the extra acceptance is gained via a deceleration of the useful beam. Some simple experiments show that the two frequency microtron works according to the theory and that the overtone part of the accelerating structure can operate without external excitation.
