Abstract
This electrostatic acceleration column has first to fifth electrodes arranged in a traveling direction of ions, which are a kind of charged particles. Then, the second electrode divided into two electrode members, which are opposed to each other across a path of the ions, and to which different electric potentials are applied to deflect the ions. Further, the electrodes arranged on a downstream side from the electrode are arranged along an orbit of ions deflected by the electrode and having specific energy.
