Investigation of Uv Photoionization Sustained Discharge for Gas Lasers
The objective of this program is to investigate and improve ultraviolet (UV) photoionization plasma conditioning techniques. The primary goals of the program are the demonstration of a UV sustained electrical discharce atmospheric pressure CO laser together with an understanding of the scalability limits of such a scheme. The dynamics of the plasma generation in the UV sustai-.°d scheme are sim...
متن کاملUV-Emission from Poly-Phase Molecular Discharge/Plasma Confined by Multi-Pole Magnetic Field
We have investigated fundamentally an effect of a multi-pole magnetic field on UV-emission from molecular gases excited by a poly-phase ac discharge/plasma. It was found that when a nitric oxide gas NO mixed with a nitrogen molecular gas was used, an intense ultra-violet (UV) irradiation ranging from 200nm to 300nm was emitted from magnetically confined regions. We have examined the dependence ...
متن کاملEmission spectroscopic study on gas-gas interactions in glow discharge plasmas using several binary gas mixtures.
Emission spectra of constituent gas species from glow discharge plasmas using argon-helium, krypton-helium, argon-krypton, and krypton-argon gas mixtures were analyzed to elucidate collisional energy transfer between these gas species occurring in the plasma. In the argon-helium mixed gas plasma, the enhancement or quenching of particular Ar II lines was observed when helium was added to an arg...
متن کاملUv Diagnostics for the Emission Line Gas in Active Galaxies
Optical diagnostic diagrams are frequently ambiguous as a test of the photoionization or fast shock models of the narrow line regions of active galaxies. Here, we present a set of UV line ratio diagrams which can discriminate between pure shock and photoionization modes of excitation, and to some extent, also discriminate shocks with ionized precursors from photoionization. These diagrams use r...
متن کاملReactive Oxygen Emission From Microwave Discharge Plasmas
Metastable oxygen atoms and molecules have received increased interest because of their function in surface modification, bio-decontamination and many other industrial applications, in addition to the role in the upper atmospheric layer chemistry. We review work on production and detection of metastable oxygen and we describe our experiments, including the development of techniques for measurem...
