A cooling system for a superconductive magnet. A cryocooler coldhead and a compressor are remotely located from the magnet. A helium-gas conduit circuit has five helium-gas paths. The first path extends from the compressor's outlet port to being in proximate thermal contact with the coldhead's first stage. The second path extends from there to being in proximate thermal contact with the coldhead's second stage. The third path extends from there to being in proximate thermal contact with the magnet's superconductive coil. The fourth path extends from there to being in proximate thermal contact with the magnet's thermal shield. The fifth helium-gas path extends from there to the compressor's inlet port. By remotely siting the cryocooler coldhead away from the magnet and using helium gas for cooling, the vibrating coldhead will not affect the magnet and the helium-gas conduit circuit can have additional branches to cool additional magnets and can have rotatable couplings for cooling rotating superconductive rotors.
