Interest in the sputtering of lithium into a gaseous medium by charged particles is associated with the possibility of excitation of large volumes of gas by the products of the nuclear reaction 6Li(n,?)3H. To simulate the processes during excitation of noble gas atom and lithium by 6Li(n,?)3H nuclear reaction products, a lithium target was fabricated. This paper presents in sufficient detail the procedure for obtaining a lithium-containing layer, the main object of research, intended for conducting experiments to study the sputtering of lithium into noble gas upon excitation by a nanosecond electron beam. The possibility of using solid lithium hydride instead of lithium in the liquid phase in a surface excitation source is discussed. The lithium target was located in the irradiation chamber of the experimental setup based on a pulsed electron accelerator. The lithium layer during bombardment by a pulsed fast electron beam is heated from 300 K up to 900 K. During heating, the luminescence spectra were recorded using a QEPro-abs spectrometer (Ocean Insight). The paper presents in-situ spectroscopic measurements of lithium sputtering into noble gas under high-speed electron beam bombardment in a wide temperature and spectral range. The temperature dependences of intensity of the emission of atoms of noble gases and lithium have been studied. The results of scientific research can be used in designing of high-power lasers pumped by an electron or ion beam.
