Abstract :
An overview is given about the influence of fast magnetic field pulses (up to 40 T/s) on components of the TOSKA magnet test facility at KfK, Karlsruhe. Such fast magnetic field changes occur during the operation of poloidal field coils and accidental plasma disruptions in a Tokamak and also during safety discharges of superconducting magnets. Induced eddy currents in surrounding conductive components can cause some detrimental damage. FEM calculations were performed in order to study the influence on critical components of TOSKA and to identify necessary modifications of the facility. The paper presents the results of these calculations
