Experimental and numerical investigation of a Hall thruster with a chamfered channel wall Project supported by the National Natural Science Foundation of China (Grant Nos. 51507040, 51777045 and 51736003), the Fundamental Research Funds for the Central Universities, China (Grant No. HIT. NSRIF. 2015079), and the Research Program, China (Grant No. JSZL2016203C006). |
(color online) Plasma density contours at wall chamfer angles of (a) 0°, (b) 18.4°, (c) 26.6°, and (d) 33.7°. Also presented is the magnetic field configuration used in the simulation. The discharge voltage is 300 V and the anode mass flow rate is 5 mg/s. |
