Webb4 II. MAIN FEATURES OF TOKAMAK MAGNETS The magnet system of a tokamak is one of the most important and expensive components of the machine. The 2001 ITER magnet system cost, for example, without auxiliary systems, represents about 25% of the total cost of the machine [2]. WebbMultiscale simulation involving slow transport and fast turbulent timescales is one amongst three key computational challenges for Magnetic Confinement Plasmas, as identified in the PRACE report “The Scientific Case for HPC in Europe 2012-2024”. Whereas in global gy- rokinetic simulation the main challenge is parallelization efficiency (global …
