New features and peculiarities of anomalous self-sustained Hall E × B discharge have been discovered. The presence of a minimum density of ions n upon the magnetic field induction B is confirmed for a wide range of discharge parameters. Likewise, the operation mode for a maximum density at the optimal values of the radial and longitudinal components of magnetic induction was discovered. Both effects are accompanied by the changes in the position of the combustion zone E × B of the discharge in the anode-cathode interval and the transformation of the distribution function of the ion energy. The threshold nature of the processes in the plasma E × B of the discharge can be manifested on the curves n = f(B) as an abrupt 3 to 4 times decrease in density upon the increase in B by not more than 10%. An abrupt increase in the density of ions (up to 16 times), occurring with a slight increase in the density of neutrals (∼1.2 times), is recorded when there are jumps of the anode layer from the anode region to the cathode one and vice versa. A thin structure of ion energy spectra explained by the isomagnetic potential jumps, which generate ion density jumps in a narrow energy range, was found. In the search for the reasons for the restructuring of the discharge and generation of isomagnetic jumps, the possible effect of nonlocal gradient-drift and electron-cyclotron drift instabilities on electron mobility and ion acceleration is briefly discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
