Short Sample Testing Facility for the Superconducting Super Collider: Requirements and Development Status.

摘要

In this paper we present the system requirements of the apparatus measuring the short sample critical current of the cable for the Superconducting Super Collider (SSC), and the current status of our development work. Key features of the system presented here are: a sample holder which clamps the samples sufficiently well such that no training quenches are required to perform critical current measurements and another which may allow for faster sample mounting; voltage tap boards using a printed-circuit technique which eliminates the necessity of soldering wires for the voltage measurements; a 1-m ling, 5-cm-bore dipole magnet with close-in iron designed to produce 7.5 T with a 6000 A excitation current; and an air-lock system that allows repeated sample changes without the magnet chamber being contaminated with air and other impurities. 7 refs., 6 figs.
