Abstract

A measurement system based on the analysis of TEMP modes in a hemispherical Fabry-Perot resonator around 145 GHzhas been optimized to give access to temperatures as low as 25 K and dielectric loss tangents at 106. The extended perfor- mance which relies on refined data acquisition and conversion methods is shown for special grades of CaF2 and Sapphire.
