测量了使用镁推进剂的2千瓦级推进器的性能指标，并与使用氙推进剂的2千瓦级推进器的性能进行了比较。在7 a的放电电流下，在200 V、1.8 mg/s的推进剂下，推力器的推力范围为34±0.8 mN，在300 V、1.8 mg/s的推进剂下，推力范围为39±1.5 mN。推功率比从200v时的24±0.5 mN/kW到300v时的18±0.7 mN/kW。在200 V放电电压下，比冲为1930±49 s，效率为23±5.0% （7 a, 1.8 mg/s）。在300 V放电电压下，比冲为2420±130 s，效率为21±6.4% （5 a, 1.1 mg/s）。采用镁推进剂的推力器性能与氙推进剂的性能进行了比较，在相同的推进剂摩尔流速下，氙为5 mg/s，镁为1.1 mg/s。氙气助推器的推力为76±1.5 mN，比冲为1550±70 s，效率为40±2.0%。
The performance metrics of a 2-kW-class thruster operated using magnesium propellant were measured and compared to the performance of the same thruster operated using xenon propellant. When operated with magnesium at a 7 A discharge current, the thruster had thrust ranging from 34±0.8 mN at 200 V using 1.8 mg/s of propellant to 39±1.5 mN at 300 V using 1.8 mg/s of propellant. The thrust-to-power ratio ranged from 24±0.5 mN/kW at 200 V to 18±0.7 mN/kW at 300 V. At a 200 V discharge voltage, the specific impulse was 1930±49 s at 23±5.0% efficiency (at 7 A using 1.8 mg/s). At a 300 V discharge voltage, the specific impulse was 2420±130 s at 21±6.4% efficiency (at 5 A using 1.1 mg/s). The performance of the thruster using magnesium propellant was compared to xenon performance at matched molar propellant flow rates: 5 mg/s for xenon and 1.1 mg/s for magnesium. The xenon-fueled thruster produced 76±1.5 mN of thrust, with a specific impulse of 1550±70 s, at an efficiency of 40±2.0% compared to the ...
