摘要
Abstract
The generation and emission of high-speed plasma clouds are fundamental to plasma energy concentration and plasma–material interactions.To ensure effective long-range transmission of high-density plasma clouds,the magnetic field must be efficiently frozen into the plasma cloud.In this study,a coaxial discharge model and a closed magnetic-island compression model were established,and the factors influencing the emission velocity of the plasma cloud were analyzed by employing typical parameter settings.The results show that with an initial voltage of 25 kV,the emission velocity can exceed 620 km/s within 20 μs.The findings offer guidance for the design of discharge structures and the selection of power supply parameters.In particular,increasing the initial voltage can significantly enhance the maximum emission velocity(currently limited to about 200 km/s in ground-based equipment),thereby laying a preliminary foundation for subsequent applied research.关键词
