J Res Natl Inst Stand Technol. 2013 Aug 19;118:301-52. doi: 10.6028/jres.118.015. eCollection 2013.We review variable-temperature, transport critical-current (I c) measurements made on commercial superconductors over a range of critical currents from less than 0.1 A to about 1 kA. We have developed and used a number of systems to make these measurements over the last 15 years. Two exemplary variable-temperature systems with coil sample geometries will be described: a probe that is only variable-temperature and a probe that is variable-temperature and variable-strain.
