Abstract

An automated system for determinations of transport current-voltage (I-V) characteristics as a function of temperature (25-125 K), magnetic field (0-1.6 T), and magnetic field orientation (-125 to +145°) is described. Currents of up to 100 A are applied either as a continuous ramp or as pulses of 2-100 ms duration. A closed-cycle helium refrigerator provides a rapid (∼45 min), convenient, cost effective, cooldown from 300 to 25 K. Control of current, temperature, magnetic field, and field orientation is fully automated and requires no user interaction. The characterization of performance of a ceramic superconductor typically involves several temperatures, fields, and orientations and requires 8-30 h to complete.
