“…As the thruster is an axisymmetric structure, in this work we use a 2D axisymmetric simulation. This model has been used to study Hall thrusters [24,25], multi-cusped field thrusters [26,27], near-wall conductivity [28], and power deposition on the wall and erosion [29]. The simulation area includes the channel and near field plume area.…”

In this work, we have carried out the simulation study on the discharge process of Hall thruster under the conditions of different neutral gas radial supply positions based on particle-in-cell method (PIC) and Monte Carlo collision method (MCC). This paper compares the two-dimensional (2D) distributions of neutral gas, plasma and the distributions of wall erosion related parameters under different neutral gas supply positions. The comparison results show that the change of the neutral gas supply position will affect the radial distribution uniformity of the neutral gas and plasma in the channel. From the comparison of the density peaks, it can be found that the neutral gas density and the plasma density peak under the upper gas supply condition are relatively low, and the plasma density peak is 22.49% lower than the density peak under the middle gas supply condition. Meanwhile, as the radial position of the gas supply moves from the lower gas supply to the upper gas supply, the position of the ionization zone also gradually moves toward the anode. The comparison results of erosion related parameter distribution show that the change of gas supply location has obvious influence on erosion rate and erosion range. In terms of erosion rate, the wall erosion rate is relatively low under the upper gas supply condition, and the peak erosion rates of inner and outer walls are 33.3% and 29.9% lower than those under the other two conditions. In terms of erosion range, the gas supply position moves from the lower gas supply position to the upper gas supply position, the erosion range gradually increases from 5 to 7.5 mm.

A decoupling method is proposed for micro-Newton thrust measurement with a torsion pendulum. The basic approach is to reduce the influences introduced by the propellant tube and wires of the thruster. A hollow aluminum tube is used to hang the torsion pendulum and is also chosen as the transport pipe for the propellant of the thruster. The electric control box of the thruster is mounted on the pendulum body, which is powered by an externally installed power supply through a liquid metal conductive unit. The control of the electric control box is performed through wireless transmission. With this design, the influences of the propellant tube and connection wires between the torsion pendulum and the outside device are reduced and the stability of the torsion spring constant of the system can be improved. The use of the liquid metal conductive unit reduces the coupling between the wires and the measurement system. The feasibility of the wireless transmission is analyzed. The error sources during the thrust measurement are analyzed, and the expected three σ uncertainty of the thrust is [Formula: see text]N for the measurement of the cold gas thruster. The scheme provides a thrust measurement with higher precision and stability.
