Abstract
PURPOSE:To obtain an energy spectrum, by repeatedly scanning magnetic field intensity at high speed simultaneously with the scanning of electric field voltage at low speed and processing integral addition to a mass peak obtained at every scanning of the magnetic field intensity. CONSTITUTION:An ion extracted from an ion source 1 is separated in accordance with an energy different by scanning applied voltage to an electric field 2 from regular voltage Vs to a zero-direction at low speed. The ion continuously separated in the electric field 2, though nextly passes through a magnetic field 3 where a scanning of magnetic field intensity is repeatedly operated at high speed, is detected by a secondary electron multiplier 4. A detected signal of the secondary electron multiplier 4 is amplified in a detection amplifier 5 and processed integral addition in a central control unit 12. This integral addition work is performed in throughout the whole range of scanning voltage in the electric field 2 to obtain an energy spectrum. The necessity for providing an ion collector between the electric field 2 and the magnetic field 3 is eliminated.
