    • PROBLEM TO BE SOLVED: To improve charge converting efficiency and beam carrying efficiency when beam energy is reduced. SOLUTION: An acceleration voltage source 5 is connected to a high voltage terminal 6, and an acceleration voltage Va is partially applied by a partial voltage resistance 7b to each acceleration electrode 7a on a low energy side acceleration tube 7 similarly to a high energy side acceleration tube 9. On the beam incidental side of the low energy side acceleration tube 7, to an acceleration electrode 7a' at a several stage from the grounding potential side, or at the third stage, for example, connecting adjustable high voltage source and a voltage of a similar degree to that when a rated acceleration voltage is applied to the acceleration tube is applied. Even when the acceleration voltage is reduced, a strong lens action is generated at an entrance part close to the grounding potensial side of the low energy side acceleration tube 7 to throttle a beam, thereby the beam introduced to a stripper canal can be increased.
