Abstract

Glow discharges have been operated at power inputs of 25 kW at 50 mb and discharge currents up to 2 A at gas flow rates of up to 0.04 kg/s in a 100 mm diameter cavity 0.5 m long. This has been made possible by the use of multiple anodes and cathodes combined with gas injection at the porous anodes. Power loading in excess of 700 kW/kg/s have been achieved. The power density of the gas (W/m3) and the current at which the glow to arc transition occurs scaled with both the number of electrode pairs and the gas flow rate through the porous anodes over the range of investigation.
