| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an ion trap type mass spectrograph in which a crosstalk current can be easily compensated.SOLUTION: An ion trap 1404 includes a ring electrode having at least one first opening, and at least one first electrode 1402 arranged at the first opening. The ion trap 1404 further includes: at least one amplifier 1408 for providing a high-frequency storage signal to the ion trap 1404; and at least one first transformer 1411 connected with the amplifier 1408 and the first electrode 1402 in such a way that the high-frequency storage signal is coupled to the first electrode 1402.
