Features of Equipment for Recording Alpha Particles as Applied to Binary Proton Technology of Radio Therapy

A spectrometer allowing recording nuclear reaction products characteristic of boron—proton radiotherapy technologies is developed. A hardware-software system of the spectrometer allows identifying alpha particles and other light products of nuclear reactions in the energy range of 0.5 MeV—10 MeV is presented. The spectrometer was tested at the Prometeus proton accelerator of the Physico-Technical Center (PTC) LPI (Protvino) and the HELIS installation of the LPI (Moscow). The spectrometer applicability to the study of the p + 11 B → 3α nuclear reaction at protons energies used in proton therapy is shown.
