摘　　要：由波荡器渡越辐射公式和电子通过wiggler边界产生的长波长辐射公式,解析给出了电子通过光学速调管时产生的长波长辐射公式．根据基本的电动力学公式数值计算出合肥同步辐射装置光学速调管的长波辐射,并将其结果与解析公式的结果进行比较．计算合肥同步辐射装置的光学速调管和弯转磁铁在红外波段范围内辐射的强度和通量,表明光学速调管有很好的性能．本文说明,光学速调管不但可以用来进行相干谐波的试验研究,也可以兼用作储存环中的红外辐射光源．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.
