A method for conceptual design of a parallel-fed voltage multiplier for electrostatic accelerator

Abstract

Electrostatic accelerators use a constant potential difference to create a suitable electric field and accelerate ions and electrons. One of the most widely used electronic accelerators in the industry, the dynamitron accelerator uses a voltage multiplier circuit to generate the voltage required for acceleration. The capacitor elements of the voltage multiplier circuit in the dynamitron accelerator are constituted of semi-cylindrical electrodes located in a columnar array. The design of this column of electrodes, also known as the voltage multiplier column, is a complex process. It requires the study and simulation of electromagnetic fields and circuit models. The conceptual design of this structure is also complicated due to parameter interdependence. In this article, after a brief introduction to different parts of the dynamitron accelerator and details of voltage multiplier columns, a process for the conceptual design of the voltage columns of a dynamitron accelerator is presented.
