一个经典的静电感应电机，卡瓦洛的乘法器，建议在低温环境中的现场生产非常高的电压。该器件适合于在非常小的负载电流的条件下产生大的静电场。本文分析了卡瓦洛乘法器的工作原理，并用系统中电极间的互电容进行了定量描述。构建了一个演示装置，并将测得的电压与基于系统中测得的电容的预测进行比较。卡瓦洛乘法器的简单性使其适合使用有限元软件进行静电分析，并且可以优化电极形状以利用高介电强度介质（例如液氦）。本文介绍了用于大型低温中子电偶极矩测量实验的卡瓦洛倍增器的设计研究。
A classic electrostatic induction machine, Cavallo's multiplier, is suggested for in situ production of very high voltage in cryogenic environments. The device is suitable for generating a large electrostatic field under conditions of very small load current. Operation of the Cavallo multiplier is analyzed, with quantitative description in terms of mutual capacitances between electrodes in the system. A demonstration apparatus was constructed, and measured voltages are compared to predictions based on measured capacitances in the system. The simplicity of the Cavallo multiplier makes it amenable to electrostatic analysis using finite element software, and electrode shapes can be optimized to take advantage of a high dielectric strength medium such as liquid helium. A design study is presented for a Cavallo multiplier in a large-scale, cryogenic experiment to measure the neutron electric dipole moment.
