Coils and power supplies design for the SMART tokamak

A new spherical tokamak, the SMall Aspect Ratio Tokamak (SMART), is currently being designed at University of Seville. The goal machine to achieve a toroidal field 1 T, plasma current 500 kA and pulse length ms for with major radius 0.4 m minor 0.25 m. This contribution presents design coils power supplies machine. foresees central solenoid, 12 8 poloidal coils. Taking waveforms these set as starting point, each them has been withstand Joule heating during tokamak operation time. An analytical thermal model employed obtain cross sections coil and, finally, their dimensions parameters. flexible modular supplies, based on IGBTs supercapacitors, presented. topologies control strategy are explained, together in MATLAB Simulink simulate performance, proving feasibility before construction system.
