Longwavelength Radiation from Optic Klystrom

This paper investigates long wavelength radiation from the electron beams passing through Optic Klystron. First, a set of formulas is given to compute the long wavelength radiation by Optic Klystron. Next, the quantities of the formulas are testified by a program based on the basic electron dynamic theory. At the end of the paper, the flux per unit solid angle and the flux of long wavelength radiation, which are from bending magnet and Optic Klystron, respectively, are compared. The result shows that for the radiation in the infrared region, Optic Klystron is superior to bending magnet. This paper shows that the Optic Klystron in the National Synchrotron Radiation Laboratory, which is used for the coherent harmonic generation FEL, can be used as a high brilliance infrared source as well.
