Study on the correlation between low-frequency oscillation characteristics of hall thruster and evolution of erosion products

Key Points

• Erosion products are closely correlated with low-frequency oscillation characteristics in Hall thrusters, affecting performance.
• Measurement revealed that specific oscillation patterns significantly correlate with the types of erosion observed during operation.
• Analysis includes examining the electrical and plasma dynamics involved in erosion processes in Hall thrusters, emphasizing design considerations.
• Such findings highlight potential improvements in Hall thruster design, enabling enhanced propulsion system longevity and efficiency.
