Abstract

The invention provides a plasma generating device and method, and the device comprises a reaction housing, two electrodes with opposite polarities, an air extractor, an air supply device, an air pressure detection device, and a control device. According to the plasma generating device provided by the invention, the air extractor strongly and rapidly extracts air in the reaction chamber at a firstrate; when the reaction chamber reaches a first set air pressure, gas for ionization is provided for the reaction chamber through the air supply device, and when the reaction chamber reaches a secondset air pressure, the high-voltage pulse power supply supplies power to the two electrodes so as to ionize the gas, so that plasma is generated in the reaction chamber; the air extractor continuouslyand slowly extracts the gas in the reaction chamber at a second rate, and the ionized gas slowly and dynamically flows in the reaction chamber in a balanced manner, so that low-pressure gas flow withrelatively stable density is generated in the reaction chamber, the fatigue of the ionized gas is prevented; and meanwhile, a relatively stable plasma ionization medium is provided.

Description

technical field [0001] The present application relates to the technical field of plasma application, in particular to a plasma generating device and a plasma generating method. Background technique [0002] When the electromagnetic wave encounters the plasma sheath during the propagation process, it is attenuated by being absorbed by it, and there will be deflection, delay, phase shift and other effects. When the situation is serious, a "black barrier" will appear. The measurement, control, communication, and guidance bring great difficulties. Therefore, the application requirements of plasma stealth penetration and seeker radar transmission through the plasma sheath for effective homing are urgently needed to carry out research on the measurement technology of terahertz wave propagation characteristics in plasma. Therefore, a stable plasma generation method is needed The device is used to carry out experimental research on the propagation characteristics of terahertz waves...
