Abstract A positive electron moderating device includes barrel body, insulating ring, grid net, moderator layer made by metal material layer of micro pore space, especially good for using form metal or clustered layer of metal fine wire, so fence or net woven by multimetal fine wires. The above said metal material in one of nickel, tungsten, tantalum, molybdenum, niobium, copper and gold. The present invention of moderating efficiency rate is about four times of the existing moderation device and it can work for long period of time under the condition of non extreme high degree of vacuum.
