Abstract
A cryogen-free superconducting magnet system includes a cryocooler configured to cool a superconducting coil. The superconducting coil is arranged inside a vacuum chamber at a distance from vacuum chamber walls. The superconducting coil includes two superconducting coil connectors galvanically connected to two current leads fed through a vacuum chamber wall to provide the superconducting coil with an electric current from outside of the vacuum chamber. Each current lead includes a first section and a second section, wherein the cross-sectional area of the first section is less than the cross-sectional area of the second section. The current leads are galvanically attached to the superconducting coil connectors and thermally connected to the first stage of the refrigerator with their respective second sections. The first sections of the current leads each include a cooling arrangement for cooling the first sections of the current leads by heat transfer to the outside at ambient temperature.
