Abstract:
Magnet coil arrangement comprising an actively shielded superconducting primary circuit (21) comprising first and second magnet windings (1,2,3 and 4,5) and being wound e.g. in winding chambers (7,8,9 and 10,11) in a supporting body (6a,6b) for generating a strong magnetic field in a working volume with a small magnetic stray field and a short-circuited secondary circuit (22) which is inductively coupled to the primary circuit (21) and contains third and fourth magnet windings (13,14,15 and 16,17), characterized in that the magnet windings (13,14,15 and 16,17) of the secondary circuit (22) per se form an actively shielded magnet coil.
