Abstract

PURPOSE:To increase dispersion of mass, by connecting in series two kinds of superposed fields one of which is that magnetic field force is acted in a direction toward the rotary center of an ion and the other is that magnetic field force is acted in a direction of dispersion from the rotary center of the ion. CONSTITUTION:The first superposed field is formed by a magnet 1 and electrodes 2, 3 and the second superposed field is formed by a magnet 2 and electrode 5, 6. To between the electrodes 2, 3 and between the electodes 5, 6, voltages from variable electrodes 7, 8 are applied respectively to perform sweep operation of field voltage on the basis of a sweep signal generated from a sweep circuit 9, then the sweep operation of the field voltage performs sweep operation of mass numbers of an ion passing through the first and the second superposed fields and incident to a collector C.
