Popis: Publisher Summary This chapter describes a method for the measurement of the electromagnetic field distribution in resonators and their shunt resistance by means of perturbing spheres passing freely through the resonator. A cavity resonator is used as a frequency discriminator in which a disturbance of the natural frequency leads to a change in the amplitude of the field. The corresponding signal is detected, transmitted to the oscillograph, and photographed. The chapter also presents the results of a study of microtron resonators. The accuracy of the determination of the shunt resistance and of the field distribution is established experimentally to be ∼ 8 per cent. The method of perturbing the field by a test body makes it possible for the magnitude and also the direction of the field components to be determined. The results of the experiments show that the presence of the ports in resonators leads to a difference between the actual field distribution and the theoretical one obtained without taking the ports into account.
