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.
发现逃逸电子的韧致辐射是托卡马克中逃逸电子的能量极限。逃逸电子束的最小和最大能量分别被证明受碰撞和韧致辐射的限制。还发现大量注入高Z气体(如氙气)可以在逃逸电子撞击壁之前终止破裂产生的逃逸电流。
