Abstract: | We present the results of investigation into radiation of a pulsed transverse discharge in neon at a pressure of 10–200 kPa.
Survey spectra of plasma radiation, time characteristics of radiation, and the effect of small impurities of water vapors
and air on the optical characteristics of a neon plasma were studied. We show that at a pressure of residual gases at a level
of 10 Pa intense OH*, NO*, and N

bands are observed in radiation of the plasma of a nanosecond transverse discharge in Ne against the background of continuous
plasma radiation, and in the spectral region with λ>400 nm radiation was observed on the Hβ 486.1 nm and NeI 585.3 nm lines, and (when P≥100 kPa) on the line at the 3s–3p-transitions of a Ne atom. The radiation intensity
of the third continuum of neon increases with pressure and with energy contribution to plasma, with its maximum being located
in the VUV spectral region (λ
max
<200 nm).
