AB - In The Budker Institute of Nuclear Physics the accelerator-based source of epithermal neutrons was invented and now operates to be used in the boron neutron capture therapy. Neutrons on the facility are generated during the threshold reaction 7Li(p, n)7Be which occurs when the proton beam is thrown on the lithium target. To control the neutron output it is necessary to monitor the parameters of the accelerated proton beam. The spatial distribution of the accelerated proton beam was measured exactly on the lithium target. Due to the interaction of protons and lithium there is an accumulation of a radioactive isotope of beryllium takes place. After experiments about neutrons generation it seems possible to track an area of beryllium storage and then restore the proton beam profile. The monitoring of gamma-quants with the energy of 0,477 MeV arising during the beryllium decay was carried out via the gamma-spectrometric complex. The main part of this complex is NaI-scintillation detector, which was pre-calibrated with energy. As a result of such kind of diagnostic the profile of the beam, its shape and characteristic size were determined and the results are depicted in this paper. Afterwards it could be used for an estimation of the total neutrons flux, its quantity, also to assess the target state and restore the proton beam profile.
