The synchrotron radiation originated from the energetic runaway electrons has been measured by a visible complementary metal oxide semiconductor camera working in the wavelength ranges of 380-750 nm in the Experimental Advanced Superconducting Tokamak [H. Q. Liu et al., Plasma Phys. Contr. Fusion 49, 995 (2007)]. With a tangential viewing into the plasma in the direction of electron approach on the equatorial plane, the synchrotron radiation from the energetic runaway electrons was measured in full poloidal cross section. The synchrotron radiation diagnostics provides a direct pattern of the runaway beam inside the plasma. The energy and pitch angle of runaway electrons have been obtained according to the synchrotron radiation pattern. A stable shell shape of synchrotron radiation has been observed in a few runaway discharges.
在先进超导托卡马克实验装置中，利用工作在380 - 750纳米波长范围内的可见互补金属氧化物半导体相机，对由高能逃逸电子产生的同步辐射进行了测量[H. Q. 刘等人，《等离子体物理与控制核聚变》49, 995 (2007)]。通过在赤道平面上沿电子靠近方向对等离子体进行切向观察，在整个极向截面测量了高能逃逸电子产生的同步辐射。同步辐射诊断提供了等离子体内逃逸束的直接图像。根据同步辐射图像获得了逃逸电子的能量和俯仰角。在几次逃逸放电中观察到了稳定的同步辐射壳层形状。
