Abstract :
We had developed four years ago a superconducting property measurement system (SPMS) that can be used to acquire electrical and thermal properties of high-temperature superconductor (HTS) tape samples. The SPMS was composed of the sample holder for mounting an HTS tape and 3 T HTS magnet, both cooled individually by conduction using a cryocooler. The maximum dimension of the HTS tape sample that could be loaded on the sample holder was 15 mm in width and 250 mm in length. The conduction-cooled sample holder was again fabricated to increase the maximum test current up to 800 A. Maximum transport current was 763 A in magnetic field intensity 3 T. The measuring temperature range was 15-50 K.
