本文计算了具有任意轴对称磁位形的等离子体中的非热韧致辐射，考虑了高光子能量下辐射截面的相对论角各向异性、磁力线在磁通表面的螺旋缠绕以及包含粒子俘获效应的电子分布函数的极向变化。在托卡马克和反向场箍缩的电流驱动过程中的快电子动力学可以通过将此计算耦合到计算电子分布函数的反弹平均相对论Fokker-Planck求解器来详细研究。已经在Tore-Supra托卡马克上测量的高场侧和低场侧硬X射线发射强度之间的不对称性[Equipe TORE SUPRA，在Proceedings of the 1 - 5th Conference on Plasma Physics and Controlled Nuclear Fusion Research，Seville（International Atomic Energy Agency，维也纳，1995）Vol.1，IAEA-CN-60/A1-5（Institute of Physics，布里斯托，英国，1995年），第1页.
The nonthermal bremsstrahlung is calculated in a plasma with arbitrary axisymmetric magnetic configuration, taking into account the relativistic angular anisotropy of the radiation cross section at high photon energies, the helical winding of the field lines on the magnetic flux surfaces, and the poloidal variation of the electron distribution function including particle trapping effects. The fast electron dynamics during current drive in tokamaks and reverse field pinches can be investigated in detail by coupling this calculation to a bounce-averaged relativistic Fokker–Planck solver, which calculates the electron distribution function. The asymmetry between high- and low-field side hard x-ray emission intensity that has been measured on the Tore-Supra tokamak [Equipe TORE SUPRA, in Proceedings of the 15th Conference on Plasma Physics and Controlled Nuclear Fusion Research, Seville (International Atomic Energy Agency, Vienna, 1995) Vol. 1, IAEA-CN-60/A1-5 (Institute of Physics, Bristol, U.K., 1995), p. 1...
