Pulsed power can provide instantaneously high power density to generate atmospheric nonthermal plasma in open air. In this paper, using two power supplies including a \(\mu \) s-pulse generator with a rise time of 300 ns and a pulsewidth of 5 \(\mu \) s and a ns-pulse generator of a rise time of 70 ns and a pulsewidth of 100 ns, pulsed gliding discharges are created with point-to-point electrodes...
Atmospheric pressure low-temperature plasma jet has become one of the hot research issues in plasma science and technology, and a plasma jet array is a tendency for plasma jet application. In this paper, atmospheric pressure low-temperature plasma jet array is generated by a one-dimensional device of two quartz tubes with a single ring electrode configuration, and the feed gas is helium. The discharge...
In this paper, diffuse discharges sustained by nanosecond pulses are obtained in air gaps with a multi-needle-to-plane discharge electrode configuration at atmospheric pressure. A repetitive nanosecond generator with a rise time of 70ns and a full width at half maximum of 100ns is employed to drive diffuse discharges. Characteristics of the diffuse discharge were investigated by analyzing voltage-current...
Nanosecond pulsed discharges have various discharge modes, such as corona, diffuse discharge, spark or arc. A dense diffuse discharge is particularly desirable for various applications at atmospheric pressure. In this paper, a magnetic-compression pulse generator was used to produce repetitive positive nanosecond pulses for excitation of a diffuse discharge. The output pulse of the generator had a...
