[Background]Tokamak plasma disruption generates a runaway current carrying enormous amounts of energy that,if not suppressed,can cause severe damage to equipment.[Purpose]This study aims to investigate the effects of injecting a deuterium-argon/neon gas mixture on a runaway current during plasma disruption.[Methods]Based on the high plasma current discharge conditions of the HL-2M tokamak device in China,numerical simulations were conducted using a fluid model in the DREAM code.Variations of plasma parameters,such as plasma current(Ip),ohmic cu...
