摘要：A basic ion optical system (2) in which the temporal focusing of ions is ensuredincludes a plurality of sector-shaped electrodes (11, 12, 13, and 14), an ion injection slit(15), and an ion ejection slit (16), which are placed on the same plane. A plurality of basicion optical systems (2) are placed in such a manner as to be mutually separated at
predetermined intervals in the direction approximately orthogonal to their planes. Theion ejection slit (16) of the lower-stage basic ion optical system (2) and the ion injectionslit (15) of the next-stage basic ion optical system (2) are connected to each other viaanother basic ion optical system (3) in which the temporal focusing of the ions is ensured.Accordingly, the flight distance can be elongated while assuredly achieving the temporalfocusing of the ions as an entire ion optical system (1), and a three-dimensional space canbe efficiently utilized to compactify the ion optical system (1).
