Applied Physics and Mathematics Annotation << Back ENERGY CHARACTERISTICS OF HIGH PRESSURE GAS PRESSURE IN STRONG LONGITUDINAL MAGNETIC FIELDS A.A. RUKHADZE, O.A. OMAROV, N.O. OMAROVA, P.H. OMAROVA Practical applications are studies of the eff ect of an external longitudinal magnetic fi eld on the parameters of a high-pressure discharge: the energy (power) released in the discharge; Electronic temperature and particle concentration; Radiation of the plasma of the channel-arc stages. As a result of experimental studies it was found that a strong longitudinal magnetic fi eld: leads to an increase in current density, conductivity, specifi c energy input; To decrease - the formation times of all stages of discharge development, transverse integral radiation, channel expansion rate; Shifts the maximum spectral density of radiation in the ultraviolet region with simultaneous generation of new spectral lines; Reducing the rate of expansion of the channel and the loss of transverse radiation increase the specifi c power, conductivity and temperature of the plasma at the channel-arc stages, creating conditions for both obtaining a hot plasma and creating a nanosecond source of ultraviolet and X-ray radiation. Keywords: plasma radiation, energy characteristics, plasma conductivity and temperature, strong magnetic fi elds, avalanche, channel-arc stage.
