Abstract: | Results are presented from a study of the characteristics of a steady-state plasma in a He/H2 mixture at high pressures. The plasma is formed in the outer region of a multielectrode corona discharge. It is shown that
molecules of helium hydride form in such a medium, and their decomposition is accompanied by continuum emission in the 350–650
nm region. The corona discharge is distributed over the length and can be used in systems for the transverse electric circulation
of the working medium of atmospheric-pressure plasma radiation sources. The reference spectra of the plasma emission and the
dependence of the relative intensity of the lines and the brightness of the bands of He

on the value of the discharge current, pressure, and composition of the working mixture are investigated.
