Abstract: The present invention relates to an apparatus and method for measuring the critical current of a superconducting tape. A continuous critical current measurement apparatus for measuring critical current of a superconducting tape while feeding a superconducting tape in a liquid nitrogen container includes wheel-type current terminals and wheel-type voltage terminals. The superconducting tape is continuously supplied and fed by a reel-to-reel device, and the critical current of the superconducting tape is measured in real time using the wheel-type current terminals and the wheel-type voltage terminals while the superconducting tape is fed at constant linear velocity in contact with the wheel-type current terminals and the wheel-type voltage terminals.

Abstract: A gravity control apparatus is provided, in which is controlled through the superconducting coil designed for generating uniform magnetic force. The gravity control apparatus includes a hollow cylindrical low temperature container; a combination of B0 coil and a symmetric and/or asymmetric gradient magnetic field generating coil having a predetermined length and inner and outer radiuses, wherein each of B0 coil and gradient magnetic field generating coil is wound onto a bobbin which is installed to the low temperature container so as to form a superconducting magnet, and the B0 coil has three solenoid coils which are arrayed in three parts with a predetermined spacing so as to generate, from the center of the B0 coil, uniform magnetic field having constant magnetic flux density; and a power unit for supplying operating current to each of coils. Thus, gravity acting on the material disposed in the hollow center of the low temperature container can be compensated with a uniform magnetic force.
