Development of a Superconducting Magnet for High Magnetic Force Field Application

Abstract

Laboratory size superconducting magnets to generate a magnetic force field of 1500 T <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> /m in a 40 mm and 50 mm diameter room temperature bore have been developed. In order to generate such a high magnetic force field, a superconducting magnet is combined with main coils and a reverse coil. The magnet can be operated in persistent mode and the field decay is less than 1 ppm/h, which means that the sample can be kept in a micro gravity environment for more than two years. This magnet will be used in various applications in the field of micro gravity application, such as protein crystal growth.
