The dielectric cavity resonator applied to electron spin resonance

The design curves for TE 01n dielectric cavity resonators, the quality factor, and the effective volume are computed from the characteristic equation of a hollow dielectric cylinder. A method for measuring relative values of the effective volume of different cavities is described. In an X-band electron spin resonance spectrometer the dielectric cavity gives a good signal to noise ratio. Advantages of the dielectric cavity resonator are described.
