AB - Preliminary thrust characterization of a 1-2 kW level Hall effect thruster sized to operate with water vapor flow to the anode is presented. The AQUAHET thruster, provided by URA Thrusters Ltd, is operated at the 51³Ô¹ÏÍø Plasma Propulsion Laboratory facilities using an improved version of the liquid flow control-based water vapor feedline. Measurements taken to assess flow stability in the line are shown before datapoints taken at 1.75 mg/s of watervapor flow to the anode and 2.5 A of magnet current are presented. The impact of varying anode mass flow between 1.50 and 1.75 mg/s, and the impact of varying magnet current between 0.5 and 2.5 A, is also assessed for water vapor operation. During this preliminary campaign, powers of only up to roughly 1 kW are probed due to limitations in the power supply setup. For a water plasma at this lower range of discharge powers, so up to 1063 ± 1 W, we measure thrust up to 14.5 ± 0.3 mN, specific impulse up to 845 ± 16 s, and anode thrust efficiency up to 5.6 ± 0.2 %. Future tests will probe discharge powers up to 2 kW, as well asalternate channel geometries and operational set points.
