Dust acoustic waves in a direct current glow discharge
An experimental investigation of dust acoustic ~DA! waves in a dc glow discharge plasma is described. The glow discharge is formed between a 3 cm anode disk and the grounded walls of a 60 cm diameter vacuum chamber which is filled with nitrogen gas at a pressure of about 100 mTorr. Dust located on a tray in the chamber is attracted into the plasma where it is trapped electrostatically. The dust...
متن کاملCharacterization of argon direct-current glow discharge with a longitudinal electric field applied at ambient air
A direct-current-driven plasma jet is developed by applying a longitudinal electric field on the flowing argon at ambient air. This plasma shows a torch shape with its cross-section increased from the anode to the cathode. Comparison with its counterparts indicates that the gas flow plays a key role in variation of the plasma structure and contributes much to enlarging the plasma volume. It is ...
متن کاملRadiation Produced by Glow Discharge in Deuterium
Radiation produced by low-voltage discharge in a gas containing deuterium was measured using a Geiger counter located within the apparatus. This radiation was found to consist of energetic particles that were produced only when the voltage was above a critical value. In addition, the emission was very sensitive to the presence of oxygen in the gas. In the presence of the required conditions, em...
متن کاملHardness and Stress of Amorphous Carbon Films Deposited by Glow Discharge and Ion Beam Assisting Deposition
The hardness and stress of amorphous carbon lms prepared by glow discharge and by ion beam assisting deposition are investigated. Relatively hard and almost stress free amorphous carbon lms were deposited by the glow discharge technique. On the other hand, by using the ion beam assisting deposition, hard lms were also obtained with a stress of the same order of those found in tetrahedral amorph...
متن کاملA glow discharge ion source with fourier transform ion cyclotron resonance mass spectrometric detection.
A glow discharge (CD) ion source has been coupled to a Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer using a four-element electrostatic lens to accelerate and focus ions generated external to the instrument's high magnetic field into its analyzer cell. Like other CD mass spectrometers, GD-FT-ICR can provide a quantitative measure of bulk analyte concentration with good pr...
