Localized wall damage from runaway electrons formed during tokamak disruptions is a serious concern for future large tokamaks like ITER. In the DIII-D tokamak, a large variety of experiments have been conducted to understand runaway electron formation, amplification, and loss; and to devise methods for avoiding wall damage due to runaway electrons following disruptions. As a result, the experiments can be broken into two categories: massive impurity injection experiments and runaway electron studies.
