Abstract
In the Institute of Nuclear Physics SB RAS the epithermal neutron source is entered into operation based on the tandem – accelerator with vacuum isolation. There was evaluated the accelerating installation components of a x-ray field causing dark current and breakdowns in accelerating gaps. The experimental measurements were carried out and the study results of the doze capacity dynamics are submitted, depending on change of a dark current in tandem accelerating gaps. The design changes of installation for prevention of occurrence of powerful X-ray radiation are offered and realized. The carried research allows setting necessary parameters for designing medical installation on the basis of an accelerator-tandem with vacuum isolation with the purpose of realization in oncological clinics neutron-capture therapy of malignant tumors.
