论文摘要
在磁性限制的融合等离子体中，失控电子（RE）的分布函数的重建提供了有关等离子体破坏过程中失控的电子束动力学的见解。鉴于对速度空间的二维，能量式的重建，在这项工作中，我们介绍了RES对Bremsstrahlung发射的重量函数的计算。重量功能允许将Bremsstrahung光谱与重新速度空间桥接，因为它们告诉了有助于特定光谱测量的速度空间区域。该结果用于研究安装在欧洲联合圆环的硬X射线诊断的速度空间灵敏度。
The reconstruction of the distribution function of runaway electrons (RE) in magnetically confined fusion plasmas gives insights on the runaway electron beam dynamics during plasma disruptions. In view of enabling a two-dimensional, energy-pitch reconstruction of the RE velocity space, in this work we present a calculation of the weight functions for the bremsstrahlung emission by the REs. The weight functions allow bridging the bremsstrahlung spectrum with the RE velocity space, as they tell the region of the velocity space that contributes to a particular spectral measurement. The results are applied to investigate the RE velocity-space sensitivity of the hard X-ray diagnostic installed at the Joint European Torus.
