在托卡马克中，逃逸电子的韧致辐射被发现是逃逸电子的能量极限。失控电子束的最小能量和最大能量分别受到碰撞和韧致辐射的限制。它还发现，大量注入高Z气体，如氙气，可以在逃逸的电子撞击墙壁之前终止由分裂产生的逃逸电流。
Bremsstrahlung radiation of runaway electrons is found to be an energy limit for runaway electrons in tokamaks. The minimum and maximum energy of runaway electron beams is shown to be limited by collisions and bremsstrahlung radiation, respectively. It is also found that a massive injection of a high-Z gas such as xenon can terminate a disruption-generated runaway current before the runaway electrons hit the walls.
