Adopting zircon pump as inspiration pump,a static state simulation equipment was designed for vacuum holding.The feasibility simulation experiment about keeping vacuum was performed,and the simulation results indicated that the pressure of this equipment was 1.4×10~(-3) Pa after vacuum holding for ten days.Based on the success of the simulation experiment,a hardtube apparatus was designed for microwave experiment by adopting MVE technology and a vacuum experiment was carried out.The experimental result showed that the pressure was 2×10~(-2) Pa after fifteen days.When the peak voltage was 330 kV,the power of output microwave was 650 MW,the width of microwave pulse was 40 ns,and the major frequency was 3.68 GHz.Compared with the experimental result of common apparatus,the output power of the hardtube apparatus was more than 30%,the pulse width was wider,the frequency was more simplex,and the stability was better.
