摘要
本文在离子波纹摆动器中 ,提出改变电子束的入射方向 ,保证离子波纹场的纵向分量为零 ,从而消除了纵向电场对离子波纹摆动器的影响。在小振幅条件下 ,给出了摆动器的工作方程 。
By changing the direction of injected electron beam in ion-ripple wiggler to ensure the longitudinal component of the ion-ripple electric field equals zero, the harmful influence of longitudinal electric field of an ion-ripple wiggler has been eliminated. Under the condition of small amplitude, the operating equations of the wiggler are given, and then, the trajectories of the beam electrons and the angular spectrum of spontaneous emission are derived.
