The fusion research facility ITER is currently being assembled to demonstrate that fusion can be
used for industrial energy production, while several other programmes across the world are also
moving forward, such as EU-DEMO, CFETR, SPARK and STEP. The high engineering complexity
of a tokamak makes it an extremely challenging device to optimise,…
Shattered pellet injection (SPI), with research started in recent years, is the current concept for the ITER disruption mitigation system (DMS) to prevent disruption-related damage. Compared with impurity SPI, pure deuterium (D2) SPI could contribute to runaway electron (RE) avoidance in ITER via a strong dilution cooling before the thermal quen…
Typically applied to non-linear simulations of MHD instabilities relevant to magnetically confined fusion, the JOREK code was originally developed with a 2D grid composed of isoparametric bi-cubic Bezier finite elements, that are aligned to the magnetic equilibrium of tokamak plasmas. To improve the applicability of these simulations, the grid-gene…
