论文摘要
我们对非相对性电磁透镜的轨道角动量(电子,正电子,质子等)进行了非相关的涡流粒子(电子,正电子,质子等)的捕获和加速度进行详细分析,这是线性加速器的典型的。我们说明了加速度以及可能由某些现实生活中的缺陷引起的电场和磁场的不均匀性。我们确定可以捕获波数据包并成功地通过镜头运输的条件。我们描述了过渡过程,并解释了如何将一个自由的拉瓜 - 高斯小包被捕获到镜头的Landau状态,从而在所有及时保存其结构。提供了几个代表性的例子来说明发达的形式主义。
We present a detailed analysis of the capture and acceleration of a non-relativistic charged vortex particle (electron, positron, proton, etc.) with an orbital angular momentum in a field of an axisymmetric electromagnetic lens, typical for a linear accelerator. We account for the acceleration as well as for the inhomogeneity of both electric and magnetic fields that may arise from some real-life imperfections. We establish conditions when the wave packet can be captured and successfully transported through the lens. We describe the transition process and explain how a free Laguerre-Gaussian packet could be captured into the Landau state of the lens preserving its structure for all moments in time. Several representative examples are provided to illustrate developed formalism.
