A new type of high voltage generator has been designed with the aim of developing a compact, inexpensive and easily maintained generator for energetic ion beam analyses such as Rutherford backscattering and particle induced X-ray emission. It consists of several rotating disks and fixed plates made of insulator with metal plates. Since the structure is similar to a rotating disk-type generator, such as the Disktron, it should basically have the potential to display indicators such as compact size and reliable generated voltage stability. Its generating mechanism is, however, rather similar to rectifier-type generators, such as the Cockcroft- Walton and the Schenkel types, so that there are no friction components which might produce a lot of dust, thus opening the high pressure tank for cleaning is an infrequent operation. The proposed generator can be produced relatively inexpensively. A single module model has been built and its generating ability was studied. As a result, it was confirmed that the proposed generating mechanism functions successfully.
