在环六旗-2A（通常称为HL-2A）重大破裂过程中逃逸电子产生的实验研究中[L. W. Yan，Nucl. Fusion 51，094016（2011）]托卡马克，已经观察到飞行中的长寿命逃逸电子束的详细的时间和空间分辨的X射线图像，并且这些允许详细分析在主要破裂中破裂产生的逃逸电子束的产生和演变，在HL-2A装置上，预破裂等离子体电流向逃逸电流的转换效率高达55%。此外，还发现从破裂开始到逃逸电子束形成之间存在约7 ms的延迟，借助于平衡FIT（EFIT）程序，磁位形重构使得详细观察主要破裂过程中磁通量的几何演化成为可能。EFIT磁位形重建结果表明，这种延迟是由于磁位形的瞬时强形变引起的。
In an experimental study of the runaway electron generation during major disruptions in the HuanLiuqi-2A (commonly referred to as HL-2A) [L. W. Yan, Nucl. Fusion 51, 094016 (2011)] tokamak, detailed time and space resolved x-ray images of the long-lived runaway electron beam in flight have been observed and these allow a detailed analysis of the generation and evolution of the disruption produced runaway electron beam in a major disruption, where the conversion efficiency of pre-disruption plasma current into runaway current is up to 55% on HL-2A tokamak. Moreover, a delay of about 7 ms between the start of the disruption and the formation of runaway electron beam has been found. With the aid of the Equilibrium FIT (EFIT) code, magnetic configuration reconstruction has made possible a detailed observation of the magnetic flux geometry evolution during major disruptions. The EFIT magnetic configuration reconstructions show that the delay is due to the transient strong deformation of the magnetic configurat...
