| Abstract | A source of epithermal neutrons based on a tandem accelerator with vacuum insulation for Boron Neutron Capture Therapy of malignant tumors was proposed and constructed. Stationary proton beam with 2 MeV energy, 1.6 mA current, 0.1% energy monochromaticity and 0.5% current stability was obtained*. The flow of charged particles accompanying the accelerated ion beam was detected and measured**. To suppress this concomitant flow cooled diaphragm, cryopump and the electrostatic ring were installed in the input of accelerator. The surface of the vacuum vessel was covered with netting to suppress secondary electron emission. These steps have reduced the flow of charged particles 25 % of the ion beam to 0.5 % and to increase the current proton beam 3 times - up to 4.5 mA. The paper presents the results of research and declares plans to use the accelerator for the BNCT. | |||||
