摘　　要：A two-stage cascade magnetic compression scheme based on field reversed configuration plasma is proposed.The temperature and density of plasma before and after magnetic compression are analyzed.In addition,the suppression of the two-fluid effect and the finite Larmor radius effect on the tilting mode and the rotating mode of major magnetic hydrodynamic instability is studied,and finally,the key physical and engineering parameters of the deuterium-deuterium fusion pulse device are introduced.Further analysis shows that the fusion neutrons can be produced at an energy flux of more than 2 MW/m^(2)per year,which meets the material testing requirements for the fusion demonstration reactor(DEMO).If the recovery of magnetic field energy is taken into account,net energy outputs may be achieved,indicating that the scheme has a potential application prospect as a deuterium-deuterium pulse fusion energy.
