Analysis of continuous generation of electron beams in medium-pressure gases

Estimation of the current-voltage characteristic of an open discharge

“…The results of approximation of the results of our measurements performed in air [1] are shown in Fig. 1; the results of measurements in helium are shown in Fig.…”

“…5. Measurements were performed in helium under a pressure of 116 Pa on the setup described in [1]. The cathode was made of molybdenum, and the EBG anode was absent (i.e., the walls of the vacuum chamber serve as the anode).…”

“…In recent years, the devices generating electron beams in a gaseous medium with moderate pressure (0.1-15 kPa), based on the effect of electron runaway from the high voltage glow discharge, have been intensively developed [1][2][3][4]. Such devices consist of a planar cathode and a grid anode (including the limit ing case of a "grid" with a single hole).…”

“…Due to this, it seems quite appropriate to use the term "open discharge" proposed in [5] and many subse quent works. To increase the hindrance of the dis charge, a dielectric with holes is sometimes placed between the cathode and the anode [1][2][3].…”

Transverse magnetic field effects on the high-voltage pulsed discharge plasma in helium

“…The effect of the magnetic field on the gas-discharge plasma has been investigated since the middle of the last century (Spitzer 1958;Sakharov 1959). The confinement of high-temperature plasma by the magnetic field is still of great interest to scholars worldwide (Blewin and Haydon 1958;Harcombe, Palmer & Gozna 1963;Huxley and Crompton 1974;Ness 1994;White, Robson & Ness 1999;Ness and Makabe 2000;Raspopovic et al 2000;Shidoji, Makabe & Ness 2001;Dujko, Raspopovic & Petrovic 2005;Hettkamp and Lindemann 2007;Bobrov et al 2013;Dujko et al 2015;Omarov et al 2018;Limpens et al 2021;Starikovskiy, Aleksandrov & Shneider 2021;Gao and Fang 2022;Rodríguez, Paul & Bhattacharjee 2022;Wang et al 2022;Li et al 2023). The influence of the magnetic field on low-temperature plasma of various types of discharges, such as glow discharge (Blewin and Haydon 1958), arc discharge (Hettkamp and Lindemann 2007), corona discharge (Gao and Fang 2022), pulse discharge (Li et al 2023) and after glow discharge (Limpens et al 2021) is also extensively studied.…”
