摘要

在这项工作中，我们研究了在弱轴向非均匀性系统中，所需的光束隧道边界形状，使得非轴对称电子束的横截面在E/spl倍/B漂移的情况下保持不变。对于椭圆截面梁(含板状梁的极限)，在非均匀性条件下对泊松方程进行了一阶求解，从而确定了合适的梁隧道边界形状。

Axially non-uniform beam-tunnel geometries preserving the cross-section of a sheet beam

In this work, we study in a system with weak axial non-uniformity, the required shape of the beam-tunnel boundary, so that the cross-section of a non-axisymmetric electron beam is preserved, in spite of the E/spl times/B drift. For a beam with elliptic cross section (including the limit of a sheet beam), the Poisson equation has been solved to first order in the non-uniformity, thus defining the suitable shape of the beam tunnel boundary.
