Electrical power is supplied to a tomography system, such as to the main superconducting magnet and gradient coils of an MRI system. Tubular electrical conductors (140, 144) are provided as ramp leads for a superconducting magnet, though which flows cooling fluid. The bore of the tubular conductor receives the cooling fluid from specific tap point (150, 156) of the cooling circuit at fluid access ports (148, 154). The conductors may be a separate circuit branching off the main coolant flow to the gradient coils, may carry the whole supply of coolant to the gradient coils or supply the coolant and power to gradient coils. |
