Abstract : The design procedure and considerations for a tunable resonant coaxial microwave cavity are discussed. The design of a practical cavity for use between 1 and 8 Kmc/sec is given. A technique for producing exponentially decaying echo envelops is described. A method of accurately measuring small changes in low attenuation rates is given. Measurements made in quartz at low temperatures and at 1000 mc/sec are described. (Author)
