Abstract

When a uniform magnetic field is superimposed on a uniform electrostatic field, the combination can act as a magnetically focused mirror. This mirror is predicted to have aberrations of opposite sign to those of a magnetic lens and may therefore be useful as a corrector. We have built an electron optical system to test these ideas. The results are presented in two papers. This first paper describes the general design and the results of the measurements of the first order properties. The second paper (Tsai, F., J. Microsc. 197 (2000) 118-135) will describe the measurements of the aberration properties.

摘要

当一个均匀磁场叠加在一个均匀静电场上时，这种组合可以起到磁聚焦镜的作用。预计这种镜子具有与磁透镜相反符号的像差，因此可能用作校正器。我们构建了一个电子光学系统来测试这些想法。结果发表在两篇论文中。第一篇论文描述了总体设计以及一阶特性的测量结果。第二篇论文（蔡，F.，《显微镜学杂志》197 (2000) 118 - 135）将描述像差特性的测量。
