研究目的
Investigating the process of microwave window breakdown at the vacuum/dielectric interface by building a dynamical model that includes the effects of gas desorption and gas diffusion.
研究成果
The dynamical model effectively describes the microwave window breakdown process at the vacuum/dielectric interface, highlighting the significant roles of gas desorption and diffusion. The model's predictions align well with PIC-MCC simulations, offering insights into the breakdown mechanism and providing a foundation for microwave window design.
研究不足
The model assumes H2 as the desorption gas for simplicity, which may not fully represent the complexity of actual desorption gases. The gas desorption coefficient's value is estimated due to unclear experimental data.
