An innovative test bench for HTS cables has been designed and is presently under construction at the Cryogenic Laboratory of the University of Ferrara and INFN-Ferrara, Italy. The aim of the test bench is to measure of the critical current as a function of tension or compression of a straight MgB_{2} and HTS wire at their working temperature. Currents up to 600 A will be supplied to a 120 mm long wire, which can be cooled down to 20 K, by cold-heads in vacuum. The piece of information from the traction bench will be synchronized with the power supply and quench protection system. As the stress is constant on the wire cross-section, the measurement of the properties of a straight-wire represents a direct measurement of the strain behavior of the HTS wire. The full mechanical design will be illustrated together with the complete DAQ system.

Abstract

An innovative test bench for HTS cables has been designed and is presently under construction at the Cryogenic Laboratory of the University of Ferrara and INFN-Ferrara, Italy. The aim of the test bench is to measure of the critical current as a function of tension or compression of a straight MgB_{2} and HTS wire at their working temperature. Currents up to 600 A will be supplied to a 120 mm long wire, which can be cooled down to 20 K, by cold-heads in vacuum. The piece of information from the traction bench will be synchronized with the power supply and quench protection system. As the stress is constant on the wire cross-section, the measurement of the properties of a straight-wire represents a direct measurement of the strain behavior of the HTS wire. The full mechanical design will be illustrated together with the complete DAQ system.
