✦ Synopsis
In this paper an electromagnetic system for a 200 kW MgB 2 induction heater was designed to verify the feasibility of MgB 2 superconductor in a DC induction heating system. The final master plan connects the electromagnetic design to the cryogenic and mechanical designs including the required measurement system. The electromagnetic design consists of conductor development, dimensioning the superconducting magnets and the quench protection system analysis. The coil system must guarantee appropriate heating distribution in the aluminium billet. The conductor has to fulfill the requirements of the current carrying capability required by the coil design. Furthermore, the conductor layout and constituent materials affect greatly to the coil stability in fault conditions. The coil behaviour during a fault was studied by quench simulations. The protection system design was based on the results of the quench analysis.
