Problems solved by technology

[0005] However, ordinary microwave-plasma interaction devices often cannot ensure whether the plasma is magnetized or not, and the degree to which it is magnetized. Therefore, a specific device is required to allow the plasma to interact with microwaves while ensuring that it is magnetized. And by changing the degree of magnetization, observe the effect and test the experimental data

Abstract

The invention provides a microwave and magnetized plasma interaction device. The device comprises a hot tungsten disc (1), a cylindrical resonator (2), a detector (3), a Langmuir probe (4), a high-frequency probe (5), a collector (6) and a sweep generator (7), wherein the hot tungsten disc (1) is connected with a waveguide tube which is arranged in a cavity of the cylindrical resonator (2), the cylindrical resonator (2) is also located in the detector (3), and one side of the cylindrical resonator (2) is connected with the sweep generator (7); after the waveguide tube penetrates through the cylindrical resonator (2), the Langmuir probe (4) and the high-frequency probe (5) are sequentially arranged on the waveguide tube, and the waveguide tube is connected with the copper collector (6) finally. According to the device, microwaves and magnetized plasma can interact according to the process preconceived by an experimenter, and parameters of the magnetized plasma and the microwaves after interaction are detected.

Description

Technical field [0001] The invention relates to an experimental device capable of realizing the interaction between microwaves and magnetized plasma under certain conditions and detecting the parameters of the microwave and magnetized plasma after the interaction occurs, and belongs to the field of electromagnetic fields. Background technique [0002] Plasma is a form of matter composed mainly of free electrons and charged ions. If the gas is continuously heated to decompose molecules into atoms and ionize, a "gas" composed of ions, electrons and neutral particles is formed. This state is called plasma. In addition to heating, there are other methods to generate plasma. However, the method used to generate plasma in this device is to use a hot tungsten disk to heat the potassium vapor to ionize it. [0003] Microwave refers to radio frequency electromagnetic waves with wavelengths between infrared and UHF. This device uses a resonator to generate the microwaves required for the ...
