Abstract
The runaway electrons (REs) during disruptions are a crucial problem, especially for the future large-scale tokamaks, which is due to the local impact of RE beams and the large thermal load on the components of the first wall. Therefore, the control and the mitigation of runaway electrons during disruption are now of special attention. In this paper, the recent studies on controlling and mitigating REs during disruptions are reviewed. The results are mainly from the HL-2A and J-TEXT tokamaks. We mainly focus on the prevailing experimental results and progress in the last 10 years: avoidance of REs during disruptions, dissipation and soft landing of RE current, and RE detection and disruption prediction. The review also discusses the direction of further developments in RE mitigation techniques for ITER and the possible pathways indicated by theoretical simulations.
