Title: Generation of uniform low-temperature plasma in a pulsed non-self-sustained glow discharge with a large-area hollow cathode

Abstract

Generation of plasma in a pulsed non-self-sustained glow discharge with a hollow cathode with an area of ≥2 m{sup 2} at gas pressures of 0.4–1 Pa was studied experimentally. At an auxiliary arc-discharge current of 100 A and a main discharge voltage of 240 V, a pulse-periodic glow discharge with a current amplitude of 370 A, pulse duration of 340 μs, and repetition rate of 1 kHz was obtained. The possibility of creating a uniform gas-discharge plasma with a density of up to 10{sup 12} cm{sup −3} and an electron temperature of 1 eV in a volume of >0.2 m{sup 3} was demonstrated. Such plasma can be efficiently used to treat material surfaces and generate pulsed ion beams with a current density of up to 15 mA/cm{sup 2}.

  • We investigate the self-pulsing phenomenon of a low current cavity discharge in a cylindrical hollow cathode in pure argon. The waveforms of pulsed current and voltage are measured, and the time-averaged and time-resolved images of hollow cathode discharge are recorded by using high-speed intensified charge coupled device camera. The results show that the self-pulsing is a mode transition between low-current stage of Townsend discharge and high-current stage of glow discharge. During the self-pulsing, the current rising time relates to the dissipation of space charges, and the decay time relates to the reconstruction of the virtual anode by the accumulation ofmore » positive ions. Whether or not space charges can form and keep the virtual anode is responsible for the discharge mode and hence plays an important role in the self-pulsing phenomenon in low current hollow cathode discharge.« less
  • The results of anodization of aluminum and silicon in an oxygen plasma are presented. The plasma was generated by a non-self-sustained glow discharge with a hollow cathode excited by an electron beam at the oxygen pressure of 20 Pa. The density of the current flowing through the anodized specimen did not exceed 1.5 mA/cm{sup 2}, and its temperature was 200-250 Degree-Sign C. Continuous Al{sub 2}O{sub 3} and SiO{sub 2} films were formed on the aluminum and silicon surfaces. The growth rate of the oxide layers was 150-200 nm/h for Al{sub 2}O{sub 3} and 400-800 nm/h for SiO{sub 2}.
  • A contactless method was developed for the determination of local characteristics of a discharge in a pulsed electron-beam-controlled CO/sub 2/ laser. An experimental study was made of the influence of the spatial inhomogeneity of the electric field on the stability of the discharge and on the laser efficiency. A method was developed for calculating the electrode geometry which made it possible to improve considerably the inhomogeneity of the electric field and to increase the laser efficiency by 15--20%.
  • Experimental study of plasma produced at the nitrogen pressure 0.2-1 Pa in the chamber volume V Almost-Equal-To 0.12 m{sup 3} as a result of injection into the chamber of a broad nitrogen molecule beam with 1-4 keV energy and 0.1-1 A equivalent current is carried out, and the study results are presented. Dependences of the plasma density distribution on the beam equivalent current I{sub b}, energy E{sub b}, and gas pressure p indicate a crucial role of fast molecules in gas ionization, and the probe characteristics reveal two groups of plasma electrons with the temperatures T{sub e} {approx} 0.4 eVmore » and T{sub e} {approx} 16 eV. Immersion in plasma of an electrode isolated from the chamber and application to the electrode of a positive voltage U result in non-self-sustained discharge. When U changes from {approx}0.5 to {approx}1.5 V, the discharge current I rapidly rises to a certain value I*, and after that the rate of rise dI/dU drops by an order of magnitude. At U {approx} 10 V, the current I rises to I{sub 0} Almost-Equal-To 1.5I*, and dI/dU once again drops by an order of magnitude. Current I{sub 0} specifies the number of electrons produced inside the chamber per second, and it grows up with E{sub b}, I{sub b}, and p. At U > 20 V, due to gas ionization by fast electrons emitted by the chamber and accelerated up to the energy {approx}eU in the sheath between the plasma and the chamber walls, the current I rises again. When U grows up to {approx}50 V, production of fast electrons with energies exceeding the ionization threshold begins inside the sheath, and the ionization intensity rises dramatically. At U > 150 V, contribution of fast electrons to gas ionization already exceeds the contribution of fast molecules, and the plasma density and its distribution homogeneity inside the chamber both grow up substantially. However, even in this case, the discharge is non-self-sustained, and only at U > 300 V it does not expire when the beam source is switched off.« less
  • Atomic level populations in the negative glow of a hollow cathode discharge were measured using a modification of the method of reabsorption. Results of population measurements on the S/sub 2/, S/sub 3/, S/sub 4/ and S/sub 5/ levels of the state 2p/sup 5/3s of neon were presented. The dependence of population on pressure, discharge current density and the presence of helium was discussed. (DDA)
