Description
At the INP SB RAS, for a promising procedure for the treatment of malignant tumors, an accelerator source of neutrons was proposed and created based on a new type of charged particle accelerator - a tandem accelerator with vacuum insulation. The accelerator produces a beam of protons or deuterons with a current range from 1 nA to 10 mA and energy from 0.6 to 2.2 MeV and generates neutrons with a cold, thermal, epithermal, , monoenergetic and fast spectrum.
Using a lithium target 88 μm thick, the fast neutron spectrum of the 7Li(d,n)8Be reaction was measured at deuteron beam energies from 1 to 2 MeV. To measure the spectrum, a UNSD-15 Mobile neutron and γ-radiation spectrometer-dosimeter was used. In the course of the research, the equipment was calibrated and the spectrum of fast neutrons was measured at a distance of 2 and 5 meters from the lithium target along the neutron beam axis.
The paper presents the results of measurements in the form of graphs of the energy spectrum of fast neutrons, as well as conclusions about the further study of the reaction spectrum of 7Li(d,n)8Be and its angular distribution.
