The invention discloses a
spacecraft potential
active control device based on a helicon wave
plasma, comprising a
discharge chamber, a
magnet and a potential control
electrode. The
magnet is externally arranged on one end of the
discharge chamber; a radio-frequency antenna is winded outside the
discharge cavity and is adjacent to the
magnet; the position of the discharge chamber working medium gas inlet of a discharge chamber working medium gas
pipe is not beyond the front end of the adjacent radio-frequency antenna; the potential control
electrode which is electrically connected with the conductive
structural element of a
spacecraft is arranged in the discharge cavity; a radio-frequency source is used for providing power supply for the radio-frequency antenna; and the working medium gas is ionized into the
plasma, under the action of the
electromagnetic field generated by the radio-frequency antenna and the
magnetic field generated by the magnet. The invention further discloses the application of the
spacecraft potential
active control device based on the helicon wave
plasma. The spacecraft potential
active control device based on the helicon wave plasma has the advantages of low
power consumption, light weight of used working medium,
high potential control efficiency, high starting frequency and is superior to the prior art in the spacecraft potential control and the
orbit energization effect
risk control.
