Design of a low energy Van De Graaff generator and accelerator

Abstract

In this study a low energy electrostatic Van de Graa® generator and asimple linear accelerator tube designs are proposed.In the present design, a high voltage (HV) spherical terminal is designedfrom copper, whose electrostatic voltage would be accumulated around 450 kVby a single ply belt driven by a standard 2 Hp monophase electrical motor forthe VDG generator part and around 60 % at that voltage would be used forthe accelerator system. The proposed design of the simple linear electrostatichigh voltage accelerator tube should be attached to the HV generator terminaldome. The sample particle source of the acceleration tube may be replaced byan electron gun or an ion source depending on later decision.Since the presented VDG generator and accelerator system theoreticallydesigned and some parameters of accelerator system, such as the position ofparticle source and the dimensions of the accelerator rings and ect., are obtainedby a well known particle accelerator simulation program instead of experimentalproduces, a matrix of experiments should be carried out after the constructionof the proposed design, to optimize the reliability of the VDG generator andaccelerator system.Key words: Van de Graa® generator, Simple linear accelerator, Design
