Abstract

The crossed homogeneous electrostatic and magnetic deflection fields of an analyser (Wien filter) have been formed by two condenser plates and two pairs of coils. The optimum operating conditions are shown to require unit magnification, contrary to the view of other authors. By varying the current ratio in the coils, a desired inhomogeneity can be introduced in the magnetic field and with this the second-order angular aberration can be corrected. The possibility of a double-focusing Wien filter is discussed.

最佳调整和修正的维也纳过滤器
用两个电容板和两对线圈形成了分析器(维恩滤波器)的交叉均匀静电场和磁偏转场。与其他作者的观点相反,最佳操作条件显示需要单位放大。通过改变线圈中的电流比,可以在磁场中引入所需的不均匀性,从而可以纠正二阶角像差。讨论了双聚焦维恩滤光片的可能性。
