Un système de mesure par câble coaxial applicable jusqu'à 60 GHz à la température cryogénique est développé à l'aide de connecteurs en V. Dans ce système, la localisation précise des antennes-cadres de couplage peut être ajustée par des étapes mécaniques tridimensionnelles dans la région des basses températures. Afin de vérifier l'utilité de ce système, la dépendance en température de la résistance de surface (Rs) de films Y-Ba-Cu-O (YBCO) a été mesuré à 30 GHz par la méthode à deux résonateurs diélectriques utilisant TE011- et TE013- résonateurs à tige saphir en mode. Le résultat mesuré de Rs était de 0.5 mΩ à 30 GHz et 20 K, soit 1/40 par rapport à ceux des plaques de cuivre.

Abstract: A coaxial cable measurement system applicable up to 60 GHz in the cryogenic temperature is developed by using V-connectors. In this system, the fine location of coupling loop antennas can be adjusted by three-dimensional mechanical stages in the low temperature region. In order to verify usefulness of this system, the temperature dependence of surface resistance (Rs) of Y-Ba-Cu-O (YBCO) films was measured at 30 GHz by the two-dielectric resonator method using TE011- and TE013- mode sapphire rod resonators. The measured result of Rs was 0.5 mΩ at 30 GHz and 20 K, which was 1/40, compared with those of copper plates.
