Edge radiation in an electron storage ring
- 112 Downloads
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.
