摘要

通过解析分析和数值模拟计算，对上海同步辐射装置（ＳＳＲ）波荡器Ｕ９．０在红外及远红外波段（波长范围８—２００μｍ）的渡越辐射谱通量密度角分布、亮度等特性进行了研究，并探讨了电子束发射度、能量散度及波荡器磁场误差对渡越辐射谱亮度的影响。结果表明，ＳＳＲＦＵ９．０的红外及远红外渡越辐射通量密度最高可达３５ｘ１０１３Ｐｈｏｔｏｎｓ／（ｓ·ｍｒａｄ２·ＢＷ），收集角φ＝０．２３ｍｒａｄ，且通量密度随电子上的发射度、能散和波荡器磁场误差等的变化很小。

Abstract

The theory of transition undulator radiation was described first

then the properties of infrared and far-infrared transition undulator radiation of SSRF U9.0 were explored by the methods of analytical treatment and numerical simulation

and the influence of beam energy spread

emittance

and magnetic field errors on transition undulator radiation was given also. It was shown that the flux density of the infrared and far-infrared transition undulator radiation of the SSRF U9.0 was high (e.g.

the maximum flux density might reach 35x1013 photons/(s·mrad2· BW)

collecting angle φ =0.23mrad

and the effects of beam energy spreed

emittance and magnetic field errors on the radiation flux density were small.
