Anode/gas distributor and Hall thruster and space equipment comprising same

The invention relates to an anode/gas distributor and a Hall thruster and space equipment comprising the same. The top end of the anode/gas distributor is provided with a top-layer buffer cavity (3), the top of the top-layer buffer cavity (3) is provided with sunken concave parts (12) which are distributed along the circumferential direction, pointed-cone-shaped anodes (4) are arranged in the sunken concave parts (12), and the pointed-cone-shaped anodes (4) are made of porous materials capable of discharging gas. According to the invention, a hole-shaped or slit gas outlet part of a traditional anode/gas distributor is effectively replaced, the effective gas outlet area is increased, and the uniformity of emergent gas is improved. The anti-sputtering and anti-bombardment capability of the anode is effectively improved, and the problem of non-uniform gas outlet caused by ion reflux coating is effectively solved; the pointed cone anode effectively improves the partial discharge electric field, and/or improves t
