带电粒子束在非线性周期场中的传输

Transport of Charged Particle Beam in Nonlinear Periodic Field

本文研究带电粒子束在非线性周期场中的传输。利用映射方法得到了与非线性周期场匹配的束流发射相图。这种束的发射相图的变化和包络线都是周期性的,且其周期等于场的周期。

In this paper the transport of charged particle beams in nonlinear periodic fields is stu- .died. By means of mapping method the emittance plots of beams matched with the nonlinear periodic fields can be obtained. The variance of emittance plots and envelopes of these beams are periodic and their periods are equal to the period of field.
