| Abstract: | The physical model of multistage depressed collectors is discussed roundly.A MDC with a refocusing system is simulated with the help of a 2.5-dimensional(2.5-D) software(Orion),in which the secondary electron effects are considered and the performance of MDC with a refocusing system is simulated really.These jobs offer a guarantee for an improvement of the tube efficiency. |

| Keywords: | multistage depressed collector refocusing secondary electron efficiency of MDC |
