在过去，离子光学的长，高压加速器管一直是一个问题，通常处理实验。基于McKibben对高压电子管的描述，主要通过几何光学和Gans方法的结合应用，发展了一阶聚焦理论。分析表明，在确定整个加速器管的聚焦、放大和其他特性之前，需要对离子源及其相关电极的光学特性进行描述。通过对麻省理工学院洛克菲勒加速器聚焦特性的分析，说明了该理论在管和简单源系统中的应用。分析所得的计算聚焦电压与实际使用的结果一致。
In the past, the ion optics of long, high voltage accelerator tubes has been a problem usually dealt with experimentally. Based upon a description of a high voltage tube presented by McKibben, a first‐order focusing theory is developed essentially through the combined application of geometric optics and Gans' method. The analysis indicates the need for a description of the optical properties of the ion source and its associated electrodes before focusing, magnification, and other characteristics of the over‐all accelerator tube can be determined. The application of the theory to a tube and a simple source system is illustrated by an analysis of the focusing characteristics of the Rockefeller accelerator at the Massachusetts Institute of Technology. The results of this analysis yield computed focusing voltages in agreement with those used.
