Paper Abstract

A measurement system is presented which analyzes between 143 GHz and 146 GHz three consecutive TEMooq modes of a hemispherical Fabry-Perot resonator mounted into a gas flow cryostat. The major factors that determine the accuracy of the observed dielectric parameters are discussed. It is found that low dielectric loss can be measured at a level of tan δ = 10-5 which is exemplified for AI2O3 studied between 90 K and 330 K.
