Flux pumps are devices to energize superconducting magnets and are embedded in the cryo-system. Therefore heat loss through current leads is eliminated allowing for more efficient cooling design. This is particularly advantageous for HTS based magnet systems which cannot be operated in a persistent mode because of the inability to form superconducting joints. We recently developed a flux pump based on YBCO thin films capable of generating currents over 200A. In this paper we investigate variations of the design by comparing a flux pump employing an YBCO coated disc with a 2G wire based system. Results are discussed with regard to voltage generation and current capacity and were used to design a prototype 1T magnet system made of 2G HTS wire. (C) 2012 Published by Elsevier B. V.
