Analysis of the parameters of a barrier discharge in Kr-I2 and Xe-I2 mixtures

An excimer emitter with pumping by barrier discharge in mixtures of zink diiodide vapors with inert gases

“…This is apparently due to the fact that the increase in the frequency in a BD utilizing a ZnI 2 /Ne mixture leads to a significant rise of the importance of factors associated with the discharge geometry: first, the surface areas of the electrodes differ significantly, because the discharge occurs in a cylinder-wire system; second, only one electrode of the emitter is coated with dielectric and the charge in one case is transferred first through a dielectric barrier and then through plasma, and in the other case vice versa, first through plasma and then through dielectric. An argument in favor of this assumption is that the oscillograms of BD current in helium [12] and Kr(Xe)/I 2 [13] were symmetric when a discharge system with two dielectrics was employed.…”

Effective emission of Xe2* and Kr2* excited by a pulsed corona discharge bounded by a dielectric barrier

“…In the case of excitation in a multi-component operating gas mixture, one may have simultaneous emission with comparable power from two or more molecules [4]. The emission efficiency of the excilamps, ranging from 5 to 50%, is dependent on the operating gas mixture and excitation conditions [5][6][7][8].…”

“…Barrier [1][2][3], [5][6][7][8], glow [3,4] or capacitive [3,9] discharges are most often used in excilamps for gas excitation. The papers [10,11] report on the availability of an effective spontaneous VUV source, based on a continuous Xe corona discharge.…”
