Nanosecond Response and Attenuation Characteristics of a Superconductive Coaxial Line

Abstract

A miniature superconducting coaxial line is described which transmits nanosecond (nsec) pulses without any measurable change in rise time. Data in regard to the temperature dependence of the bandwidth over the range 293°K to 4.2°K are presented. The investigation is confined to ten and hundred foot lengths of cable.
