A plasma generation apparatus, and a plasma thruster configured to use the plasma generation apparatus are disclosed. The plasma generation apparatus includes a discharge vessel, a light-emitting monitor, a probe measuring instrument, a control device, and an optical axis driving unit. The discharge vessel is configured to ionize gas which is introduced to an inside thereof so as to generate plasma. The light-emitting monitor is configured to measure electron density of the plasma by emission spectra of the plasma. The probe measuring instrument is configured to measure the electron density of the plasma by a probe in the discharge vessel.

Plasma which is supplied from a supply passage () is accelerated with a Hall electric field (E) which is generated through interaction of electrons (e) emitted from a cathode (), a radial direction magnetic field (Bd), and an electric field (Ex).

Plasma accelerating apparatus and plasma accelerating method

A plasma accelerating apparatus includes: a cathode () configured to supply electrons to a plasma acceleration region; an anode (); a power supply () configured to apply a voltage between the cathode and the anode; a supply port () arranged on an outer circumference side of the cathode to supply a propellant to the plasma acceleration region; and a first magnetic field generator () configured to generate a first axial direction magnetic field in the upstream side region of the plasma acceleration region to suppress electrons supplied from the cathode from heading for the anode. Thus, the plasma accelerating apparatus and the plasma accelerating method having high thrust efficiency is provided.

Electrodeless plasma is supplied to a space between a cathode and an anode such that a resistivity in the space is reduced. The electrodeless plasma is accelerated with Lorentz force induced by a radial direction magnetic field component and an axial direction magnetic field component that are generated in the space, and current in the space.
