The flow rate and the temperature are obtained from the actual situation during the experiment and the velocity is calculated according to the grid voltage(~1000 V).The thruster exit plane is the entrance of xenon atoms,single charged ions and double charged ions.Particles are ejected following the distribution shown in equation(2).Otherwise,the mass flow rate of the neutralizer cathode is about0.13 mg s-1,and the coupling voltage is about 20 V(17–23 V).The cathode primarily affects the near-field around the thruster exit on the plane including the axes of cathode and thruster,and has little effect on the far field.Accordingly,in the current study,we neglect the effect from the cathode.Moreover,the thruster exit is supposed to be electronically grounded in this study.
