Construction of Electrostatic Accelerator with a Maximum Energy of 200keV

Following the successful design and construction of a 150keV accelerator tube, the construction of a 200keV electrostatic accelerator system at the Physics Department of the Nuclear Science Research School has been completed. This accelerator includes a 200keV accelerator tube, a high voltage power supply capable of supplying 200kV at 10mA current and a 200kV isolating transformer. An RF type ion source with a system for the control of ion beam could provide ions to the accelerator system. The vacuum system employed is a turbo molecular pumping system coupled with a mechanical rotary pump, where they can provide clean vacuum in the order of 7-10 Torr. In this paper the design criteria and some technical details of the construction of the accelerator system are presented. The construction of this accelerator provides a useful tool for research in various fields and gives an opportunity for the Iranian industry to develop and build accelerator components such as RF, vacuum and accelerator control systems.
