[Introduction]The inertial electrostatic confinement(IEC)fusion facility is a small fusion device.This paper aims to solve the problems of IEC fusion devices,such as the cathode melting,the very low Q value,and so on.[Method]This paper first analyzed the reasons for these problems,and then a new type of inner ion source IEC fusion was proposed to decrease the ion loss during the confinement process,solve the cathode melting,and increase the vacuum in the device and the Q value.[Result]At last,the improvement of neutron yield is qualitatively analyzed through the estimation,the very complex ion motion inside the fusion device is simulated through numerical simulation calculation,and anisotropic ion motion trajectories are obtained.[Conclusion]Based on estimation and numerical simulation results,the feasibility of the IEC with an inner ion source is confirmed,which can solve the problems of cathode melting and low Q value.
