Winding, cooling and initial testing of a 10 H superconducting MgB2 coil for an induction heater

A 10 H superconducting MgB2 coil, suitable for an induction heating application, has been wound, cooled and initially tested. Eight kilometres of MgB2 tape were first insulated and then wound into double pancake coils before being assembled into the complete coil. The process is described in detail, focusing on hands-on experience gained, especially regarding the different steps in the wet-winding technique used. The insulation, soldering, winding and cooling techniques applied proved practical for manufacturing of the large MgB2 coil. The complete coil was cooled by conduction cooling to 8 K and tested with a current of 185 A.
