Abstract
Disruption is an issue that need to be noticed for the future operation of tokamaks. The problem of runaway electrons during disruption needs more attention. RMP and SPI are both favorable application to mitigate runaway electrons in most of tokamak devices, the feasibility of their synergistic work need to be evaluated in simulation. Using the NIMROD and ASCOT5 codes, simulations analyze RE dynamics under combined RMP-SPI effects, focusing on RMP pre-penetration time, pellet size, and different RMP modes. The findings highlight the complex interplay between RMP and SPI in RE suppression, providing insights for optimizing disruption mitigation in future devices like ITER.
