A new superconductor joint, named the ''Pipe Pressing Method'', has been developed and the characteristic of the joint was investigated considering its application to Heliotron F and G which are being designed as the next reactor models of Heliotron E at Kyoto University. We have observed that this joint is almost superconducting. The critical current density of the joint at 6 Tesla is 310 A/mm/sup 2/ which is about one third that of the original superconductor. The voltage drop across the joints is less than 2/sigma phi/V. Utilizing this method, the total cooling power for the superconducting coil system for Heliotron G reactor is estimated to increase at most several percent.
