电子在均匀电场中的偏转可以用来测量其能量分布的众所周知的原理已经在理论和实验上进行了研究。简单的理论表明，用于这种测量的仪器的参数的特定选择。设计方程，给出了一个实际设备的尺寸，并讨论了必要的相关电路。这种类型的仪器仅采用电场，尺寸小，易于构造，并提供能量值的线性标度。根据这种设计建造的分析器总长度为5英寸，能够完全分离能量相差2%的电子。
The well‐known principle that the deflection of electrons in a uniform electric field can serve to measure the distribution of their energies, has been investigated both theoretically and experimentally. Simple theory suggests a particular choice of parameters for an instrument intended for such measurements. Design equations are presented, dimensions of a practical device are given, and the necessary associated electric circuits are discussed. An instrument of this type employes only an electric field, is small in size, is easily constructed, and provides a linear scale of energy values. An analyzer built to this design with an over‐all length of five inches was able to completely separate electrons having a difference in their energies of two percent.
