[1] Vuv emission generation at helium plasma recombination / V. V. Ivanov, K. S. Klopovskiy, A. A. Kopytin et al. // ICPIG XXIII, Proceedings of contributed papers, 17-22 July 1997, Toulouse, France. — Vol. 3. — Toulouse, France, 1997. — P. 40–41. At present time there is uncreasing interest to mercury-free luminescent sources having comparable efficiency as the current mercury-based ones. The choice for the rare gas is explaned by a number of factors - available emiting transitions, requirements of efficiency, ecology, safety, reliability and etc. The existing devices use as rule one of the self-sustained discharge schemes that limits the emission generation efficiency at definitive and often not enough high level. The reduction of rediced field in plasma permits significantly to increase the discharge system efficiency, therefore the transition to non-selfsustained discharge system when gas ionization is provided by an external ionizator could be one of the most effective approaches to VUV emission generation problem. Besides, under these conditions a plasma recombination itself can notiably contribute into emitting state excitation. We have attempted to realize and investigate this approach for xenon-helium mixture by using the open spectroscopic analysis. Here we present the main results of the experiments on VUV emission generation in helium open discharge plasma.
