On electron bunching and stratification of glow discharges

Abstract: Plasma stratification and excitation of ionization waves is one of the fundamental problems in gas discharge physics. Significant progress in this field is associated with the name of Lev Tsendin. He advocated the need for the kinetic approach to this problem contrary to the traditional hydrodynamic approach, introduced the idea of electron bunching in spatially periodic electric fields, and developed a theory of kinetic resonances for analysis of moving striations in rare gases. The present paper shows how Ts… Show more

“…Striations have been observed and extensively reviewed [13][14][15][16] in dc-driven long cylindrical devices in the low to moderate pressure regimes in which p g RՇ10 Torr À cm, where p g and R are the gas pressure and discharge radius, respectively. Both fluid 15,[17][18][19][20][21] and kinetic 16,[22][23][24] models were developed in this regime. Conditions for instability in a fluid model that indicated the importance of negative ions were developed 20 and reviewed.…”

“…Conditions for instability in a fluid model that indicated the importance of negative ions were developed 20 and reviewed. 14,15 However, more recent studies 16,[22][23][24] and experiments [25][26][27][28][29][30][31][32] indicate that if kinetic effects are included, negative ions are not required to observe striations.…”

“…Peculiarities of electron bunching and kinetic resonances are described in a separate paper in this issue. 6 Striations are a common feature of DC glow discharges; they were described in several reviews and books. 49 Moving striations appear as a combination of electron-induced ionization and ion transport in self-consistent electric fields.…”

“…Tsendin's contributions to the theory of ionization waves (striations) in rare gases are reviewed in a separate contribution to this volume. 6 The third part of the present paper illustrates applications of theoretical methods to the analysis of gas discharge phenomena. We have witnessed in several cases how new phenomena, first observed in numerical experiments, were later explained by Tsendin using his "analytical methods."…”

“…In the DC negative glow, e.g., the cold-electron temperature is established by a balance between cooling in elastic collisions with gas atoms, and heating due to Coulomb collisions with hot electrons. 8 Coulomb collisions, likewise, influence the trapping of electrons in potential wells related to striations in gas discharges, 9,10 modify the velocity distribution function and transport coefficients of electrons 11 , and affect the development of negative differential conductivity. 12 They play an import role as well in dense plasmas.…”
