Abstract
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.
