Abstract
The present invention provides a neutral beam injection power feedback control method, which belongs to the field of neutral beam injection, and studies the optimal matching relationship of operating parameters of the ion source by analyzing the ion optical characteristics of a hot cathode ion source so as to expand the optimal operating range of the ion source. Based on this, linear dynamic control of injection power in a single injection cycle is completed so as to form an operation mode based on plasma feedback. The process provided by the present invention includes the following two methods. Method 1, the beam power is dynamically adjusted under constant extraction energy. Method 2, under variable extraction energy, the tracking control of probe setting value is completed to realize the dynamic adjustment of beam power under variable energy. The present invention proposes a study protocol of continuously varying beam energy or beam power in a single injection cycle discharge to develop a study of dynamic control of injection power.
