CONSTITUTION: A hole 5 arranged in one wall 4 of an ion trap 10 is dislocated sideways to the symmetry axis 16 of the trap extending in parallel to a magnetic field. Therefore, a beam enters an area where an electrostatic field in the trap 10 has a crossing component to the axis 16 by electric potential impressed on the wall 4. As a result, when an ion enters the trap 10, the ion is refracted by a magnetic field B and the electrostatic field in the trap, and slips out of its rectilinear orbit. An impulse component in the ion axis 16 direction is decelerated to speed or less necessary for the ion to instantly escape from the inside of a cell. In this way, since the dwell time of the ion entering the trap increases, the ion is accumulated in this staying time, and very high ion density can be obtained.
