| Abstract: | It is the kernel mission and aim to improve multistage depressed collector (MDC) efficiency in the design and application. The physical model of MDC is analyzed and power distribution in it is illustrated in this paper. According to the power distribution picture, which is based on the electron initial condition in MDC, we can optimize the MDC efficiency and obtain the optimal electric potentials. On the vicinity of the potentials MDC could be simulated. In short, this way reduce the blindness in selecting potentials and facilitate the MDC design. |
