Description
Summary:The report is devoted to the results of the numerical study and optimization of the double-gap vircator with electromagnetic feedback in CST Particle Studio. The optimal geometrical parameters of this generator when it demonstrates the maximal efficiency were defined for the different working frequencies. The dependencies of the double-gap vircator efficiency on the geometrical parameters were analyzed in the optimal region. The physical processes occuring in the optimized generator were investigated.
