摘要

对球形静电分析仪的性质进行了广义相对论分析，并应用于一些特殊情况。对于允许的动能存在一个重要的限制:当能量大于某一动能Tmax时，球面分析仪不是有效的聚焦仪器。推导了速度和能量色散以及分辨率的表达式。简要讨论了分析仪中心角大于3π2且具有良好聚焦性能的特殊情况。

Relativistic theory of the spherical electrostatic analyzer

A general relativistic analysis of the properties of spherical electrostatic analyzers is presented, and applied to some special cases of interest. An important limitation on the allowable kinetic energies is shown to exist: for energies greater than a certain kinetic energy T_max, the spherical analyzer is not an effective focusing instrument. Expressions for the velocity and energy dispersions, and for the resolving power, are derived. A special case, in which the central angle of the analyzer is greater than $3π 2$ , and which has desirable focusing properties, is briefly discussed.
