Intense On-Axis Plasma Production and Associated Relaxation Oscillation in a Large-Volume Helicon Source
A helicon wave mode with a peak downstream density of greater than 1018 m-3 in argon that exhibits bright ArII emission along the axis has been characterized. The experimental conditions are: Ar gas pressure of 1-5 mTorr, external magnetic field of 70-150 G and radio frequency (rf) power input between 2 and 4 kW a 13.56 MHz using a double half-turn antenna into a source of 9 cm inner radius and 50 cm length that opens into a diffusion chamber 45 cm radius and 200 cm length. Radial profiles of...[Show more]
