abstract = {{An accelerator-based source of epithermal neutrons was proposed and created at the Budker Institute of Nuclear Physics. It consists of a vacuum-insulated tandem accelerator for producing a proton beam and a lithium target for generating neutrons as a result of the 7Li(p, n)7Be threshold reaction. With the use of a video camera and a spectrometer, the luminescence of lithium was registered when the lithium target was irradiated with protons. The recorded emission line 610.3 ± 0.5 nm corresponds to the electronic transition in the lithium atom 1s23d -> 1s22p, and the 670.7 ± 1 nm line corresponds to the 1s22p -> 1s22s transition. Based on the results of the study, the visual diagnostics for operational monitoring of the position and the size of the proton beam on the surface of a lithium target was developed and put into operation. The diagnostics can be applied in the neutron generation mode. The possibility of detecting luminescence made it possible to ensure the reliability of measuring the current of the argon ion beam accompanying the proton beam. When studying the blistering of a metal upon implantation of protons with an energy of 2 MeV, luminescence could lead to an overestimation of the surface temperature measured by a thermal imager.}},
