Ion-acoustic double layers in magnetized positive-negative ion plasmas with nonthermal electrons

“…This type of plasma has a great importance to various fields of plasma science and technology. The existence of a considerable number of negative ions in the Earth's ionosphere (Massey 1976;Swider 1988;Portnyagin et al 1991) and cometary comae (Chaizy et al 1991) is verified. Positive-negative ion plasmas are found in plasma processing reactors (Gottscho and Gaebe 1986), in neutral beam sources (Bacal and Hamilton 1979) and in low-temperature laboratory experiments (Jacquinot et al 1977;Nakamura et al 2001;Ichiki et al 2002).…”

“…For more than four decades, negative ion plasmas attracted attention due to their importance both in laboratory experiments and in space plasma observations (Massey 1976;Jacquinot et al 1977;Bacal and Hamilton 1979;Gottscho and Gaebe 1986;Swider 1988;Portnyagin et al 1991;Chaizy et al 1991;Shibayama et al 1996;Nakamura et al 2001;Ichiki et al 2002;Coates et al 2007;El-Labany et al 2010;El-Taibany et al 2011;Sahu 2011). Negative ion plasma is a plasma that contains both negative and positive ion species as well as electrons.…”

Coexistence of negative and positive polarity electrostatic solitary waves in ultradense relativistic negative-ion-beam permeated plasmas

“…Negative ion plasmas (NIP) have also been observed in Space environments, e.g. in the D and F regions of the Earths ionosphere [15,16] and in the inner coma of comet Halley [17]. Negative ion plasmas are used in industrial applications, such as neutral beam injection relying on a negative ion source to achieve plasma heating in plasma etching [18], in material processing [19] and in fusion reactors [20].…”

K-dV and mK-dV equations for solitary waves in negative ion plasmas with non-Maxwellian electrons

Mehdipoor e-mail: mostafa.mehdipoor@ghec.ac.ir processing reactors (Gottscho and Gaebe 1986) and low temperature laboratory experiments (Jacquinot et al 1977;Nakamura et al 1977;Weingarten et al 2001;Ichiki et al 2002). Also, negative ion plasmas are found in many space observations such as the D-and F-regions of the Earth's ionosphere (Portnyagin et al 1991). Linear and nonlinear propagation of IA waves in negative ion plasmas have been studied by many authors.…”
