Abstract
In order to simplify a power circuit, a linear ion trap () according to the present invention includes: two first rod electrodes () facing each other across a central axis (C), each of the first rod electrodes having an opening (); two second rod electrodes () facing each other across the central axis, in a direction different from the direction in which the two first rod electrodes face each other; and a pair of end electrodes () respectively arranged outside the two end faces of the two first rod electrodes and the two second rod electrodes. A controller () is provided to control a radio-frequency voltage supplier () which applies a radio-frequency voltage for capturing ions to each of the two second rod electrodes, and an excitation voltage supplier () which applies a voltage for resonance excitation to each of the two first rod electrodes.
