The invention relates to a
plasma generation device, which relates to the technical field of plasmas and comprises a first grid
electrode, a second grid
electrode and a
magnetic field generation component, the first grid
electrode and the second grid electrode are arranged in parallel, and a first distance is arranged between the first grid electrode and the second grid electrode; the first distance is a distance of
Debye length magnitude; the first grid is connected with the power supply
assembly; the
magnetic field generating component is used for generating a
magnetic field parallel to the first grid; during working, the power supply
assembly applies
radio frequency voltage to the first grid electrode, so that a first alternating
electric field is generated between the first grid electrode and the second grid electrode, electrons in the first alternating
electric field enter the magnetic field after
resonance acceleration, and then rotate back to the first alternating
electric field in the magnetic field to continue
resonance acceleration so as to generate
plasma; the period of the first alternating electric field is the same as that of the magnetic field. The
plasma generator is high in
discharge efficiency under low air pressure, and can generate plasmas with good radial uniformity.
