In this work proportional electroluminescence (EL) in gaseous argon with a minor (9 ppm) admixture of nitrogen has been studied. The effect of enhancement of the EL yield and the presence of a UV component in proportional electroluminescence in two-phase Ar were confirmed. On the other hand, the effect of EL yield enhancement can not be explained by a UV contribution. The results obtained are relevant in the field of noble-gas liquid detectors for dark matter search and low-energy neutrino experiments.

Keywords:
Dark Matter detectors, proportional electroluminescence in noble gases, two-phase Ar doped with N2, two-phase Cryogenic Avalanche Detectors.
