Abstract
A first ion transport unit with an ion funnel structure having high acceptance is arranged in the front half and a second ion transport unit with a Q-array structure having low emittance and high gas conductance is arranged in the rear half, and an aperture electrode to which only direct current voltage is applied is provided between them. The inside diameter of the opening of the aperture electrode is made larger than the inside diameter of the opening of the ring electrode at the last stage of the first ion transport unit, and the inscribed circle diameter of the first stage electrode plate of the second ion transport unit is made larger still. As a result, interference of high frequency electric fields between the first ion transport unit and the second ion transport unit 14 is reduced and ions which have exited the first ion transport unit are inputted at low loss into the second ion transport unit.
