Abstract:
The coupling discharge of hollow cathode in ion thruster and hall thruster is significantly different from its independent discharge with flat electrode, mainly manifested in different working characteristics and greatly shortened service life.Based on the fact that the design life of hollow cathode is significantly different from its actual life in thruster, the main reasons for the shortening of the life of hollow cathode in thruster were analyzed, the influence of electric field, magnetic field and background neutral gas density on the life of hollow cathode was summarized, and the main research contents that need to be further deepened were put forward.
