(Function) When the acceleration power source and the extraction power source are connected in series, the ions generated in the ion source are given relatively high energy according to the sum of the voltages of both types of sources, and the target is given a relatively high energy. Ion implantation can be performed using ion energy. When implanting ions into a target with low ion energy, a selection switch is operated, which disconnects the acceleration tube from the acceleration power source and instead connects the power terminal of the ion source to the acceleration power source, and at the same time connects the ion source to the acceleration power source. The power terminal of is connected to the shorting mechanism via a resistor. Ions extracted from the ion source are decelerated in the acceleration tube by the difference between the extraction power source and the acceleration power source, and a dummy current flows through the acceleration power source through the resistor and shorting mechanism, so the current flowing through the acceleration power source is converted into a positive current. It can operate normally regardless of the accelerating power source and the environmental atmosphere, and ions can be stably accelerated with low energy.
