Inspacecraft propulsion, aHall thrusteris a type ofion thruster in which thepropellantis accelerated by anelectric field. Hall thrusters trap electrons in amagnetic fieldand then use the electrons to ionize propellant, efficiently accelerate theionsto producethrust, and neutralize the ions in the plume. Hall thrusters are sometimes referred to asHall effectthrustersorHall current thrusters. Hall thrusters are often regarded as a moderatespecific impulse(1,600 s)space propulsiontechnology. The Hall effect thruster has benefited from considerable theoretical and experimental research since the 1960s.
在航天器推進中，霍爾推力器是離子推力器(ion thruster)的壹種，霍爾推力器有時也稱為霍爾效應推力器Hall effectthrusters或霍爾電流推力器Hall current thrusters。霍爾推力器壹般被認為是具有中等比沖(1600s)的空間推進技術。霍爾推力器自1960年代以來在理論和試驗研究上取得了很大進步。
Hall thrusters operate on a variety of propellants, the most common beingxenon. Other propellants of interest includekrypton,argon,bismuth,iodine,magnesium, andzinc.
霍爾推力器可使用多種推進劑，最常用的是氙。其他推進劑包括氡、氬、鉍、碘、鎂和鋅。
Hall thrusters are able to accelerate their exhaust tospeedsbetween 10–80km/s (1,000–8,000sspecific impulse), with most models operating between 15–30km/s (1,500–3,000s specific impulse). The thrust produced by a Hall thruster varies depending on the power level. Devices operating at 1.35kW produce about 83mN of thrust. High power models have demonstrated up to 3N in the laboratory. Power levels up to 100kW have been demonstrated by xenon Hall thrusters.
霍爾推力器噴氣速度最大可達10-80km/s（比沖1000 - 8000s），但絕大多數型號噴氣速度在15-30km/s (比沖1500 - 3000s)。霍爾推力器推力與功率有關。1.35kw的推力器可產生83mN的推力。高功率型號在實驗室環境中推力達到了3N。100kW功率量級的氙氣霍爾推力器也已得到驗證。
