Abstract
A Ne-liquefaction system and cryostat has been developed and built to characterize the electrical and mechanical properties of HTS conductors at elevated temperatures. The device makes use of a coil type condenser inside the experiment dewar, which is fed by LHe. Ne-gas entering the dewar at room temperature, liquefies on the coil windings and drips to the bottom of the dewar, where the experiment is located. He-gas and Ne-gas are recovered. Approximately 1.5 l of LNe was condensed into the dewar in about 1 h after precooling of the dewar. The device has been used successfully to measure zero-field and in-field transport properties of Bi-2223 and YBCO high-temperature superconductors at 27 K.
