在比临界波长长的波长处，从电子存储环中的偏转磁体边缘发射的辐射可能比标准同步加速器辐射更亮。该“边缘辐射”具有远场分布，其对于波长范围几乎与波长无关。这个范围的最小波长由使电子偏转1/γ阶角所需的距离决定，其中γ是相对论质量因子。该范围的最大波长是由直段的相对端处的边缘辐射源之间的孔径和相消干涉引起的。
At wavelengths long compared to the critical wavelength, the radiation emitted from a bending magnet edge in an electron storage ring may be brighter than standard synchrotron radiation. This “edge radiation” has a farfield distribution which is nearly independent of wavelength for a range of wavelengths. The minimum wavelength of this range is determined by the distance required to deflect an electron through an angle of order 1/γ, where γ is the relativistic mass factor. The maximum wavelength of this range results from apertures and destructive interference between the edge radiation sources at the opposite ends of the straight section.
