A Study on the Fabrication and Design of Superconducting Tunnel junction for Millimeter Wave Mixers
밀리미터파 믹서용 초전도 턴넬 접합 설계와 제작에 관한 연구
Abstract
Because of their high sensitivity and moderate bandwidth, superconducting receivers with SIS (Superconductor Insulator Superconductor) tunnel junction mixer are now widely used for millimeter wave radio astronomy. In this paper we have introduced how to determine the parameters of SIS tunnel junction which have to be optimized to achieve a good mixer performance. From these results of optimized junction parameters determined by this methods, SIS junctions which consist of a series array of four Nb/Al-AlOx/Nb junctions with each area 3.4
