A wiggler mechanism for SASE-FEL;
一种SASE-FEL用摇摆器机制探讨
In the FEL experiment,when electron beam passes through the wiggler,because of the periodical magnet field,the movement of electron beam will be changed to wiggle in the wiggler.
在FEL实验中,电子束通过摇摆器,一方面由于周期性磁场作用,电子束轨迹要周期性的摆动,另一方面还要辐射同FEL辐射波长一致的自发辐射,该辐射谱反映电子束、摇摆器集成后的参数。
Basing on these formulae,we have got full three-dimension expressions for magnetic field of periodic array wiggler with permanet-magnets and two-dimension expressions for magnetic field of six types of one-component periodic array wigglers.
