The paper describes the technology of creating a surface source of high-energy tritium ions and alpha particles formed as a result of a nuclear reaction of the interaction of the 6Li isotope with thermal neutrons .

Different design versions of the developed irradiating ampoule devices are presented, and a description of the experimental reactor facility is given. The paper also describes the scheme of reactor experiments to study the spectral-luminescent characteristics of nuclear-excited plasma of argon. The results of test experiments are presented, and they show the applicability of high-energy tritium ions and alpha particles for nuclear excitation of luminescence of inert gas mixtures.
