| Abstract |
In the BINP SB RAS was proposed and created a source of epithermal neutrons for BNCT. The proton beam is obtained on a tandem accelerator with vacuum insulation. Sectionalized demountable feed through insulator is an integral part of the accelerator. Voltage from the high voltage source is distributed to the electrodes via resistive divider. Because of the small amount of current (hundreds of microamperes) flowing through the divider, dark currents that occur in the accelerating gaps, can significantly affect the uniform distribution of the potential along the accelerating channel, and, consequently, on the beam transportation. Therefore there is a need to change the design of the feed through insulator which will allow to set potentials at the electrodes directly from the high voltage rectifier sections. To study the feasibility of such changes has been designed and built an experimental stand, in which a single insulator with double height subjected to the same conditions as in accelerator. On the experimental stand was studied electrical strength of ceramic and polycarbonate insulators with a different shape of the surface. The paper presents the results of experimental studies of insulators. Their application will get rid of the voltage divider inside the feed through insulator and realize the scheme which allows to set potential on the electrode gaps directly from the rectifier section. This will increase the operating voltage of the accelerator and its reliability.
