Abstract

PURPOSE:To improve the resolution by forming concave the outer periphery of a magnetic field for mass dispersion. CONSTITUTION:An energy analysing part with a deflection angle of nearly 90 degree is constituted with double troidal electrodes 2, 2'. A mass dispersing part 1 with an even magnetic field and a deflection angle of nearly 90 degree is provided. The outer periphery of the magnetic field which forms the mass dispersing part is formed concave, and the inner periphery is inclined by 6 to 14 degree to the negative side from the vertical of the optical axis in a plane containing the optical axis of the ion optical system.
