Abstract

The invention relates to a microwave and plasma interacting device in magnetic plasma, in particular to a microwave and plasma interacting device in magnetic plasma under the condition that a magnetic field and an electric field are perpendicular. The microwave and plasma interacting device aims to solve the problem that no microwave and plasma interacting device under the characteristic situation of the different magnetic plasma exists in the prior art. The microwave and plasma interacting device comprises a microwave generator, a ferrite isolator, an attenuator, a directional coupler, a waveguide tube, an insulation microwave window, a vacuum cavity, a plurality of solenoids, a diaphragm, a plasma source, two Langmuir probes, a cut-off tube, a matching microwave load, a loop antenna, a magnetic probe, an electrostatic probe, a multiple-grid probe and a plasma visualizer, wherein the plasma source is a sparking plasma source, generated sparking voltage is used for controlling the density of the plasma, and the attenuator is used for adjusting microwave power. The microwave and plasma interacting device is used for researching the interaction between the microwave and the plasma under the characteristic condition of the different magnetic plasma.

Description

technical field [0001] The invention relates to a microwave and plasma interaction device in magnetized plasma. Background technique [0002] In 1879, Sir William Crookes classified plasma as the fourth state of matter. According to this point of view, when a substance is heated from a low temperature, it gradually melts from a solid to a liquid, and then evaporates to a gas. Finally, if the heating is continued further, the temperature rises, and the individual atoms will split into many electrons and positively charged ions, forming the fourth state of matter, plasma. The term plasma was proposed by Irving Langmuir in 1982, which means an approximately electrically neutral collection of ions and electrons. It may, but does not have to contain a background neutral gas, which responds to electric and magnetic fields. The main feature of plasma that is different from ordinary gas and ordinary ionized gas is that the particles in this collective interact with each other thr...
