摘要： In a charged-particle beam apparatus having a high-accuracy and high-resolution focusing optical system for charged-particle beam, a group of coils are arranged along a beam emission axis to extend through the contour of radial planes each radiating from the beam emission axis representing a rotary axis and each having a circular arc which subtends a divisional angle resulting from division of a circumferential plane by a natural number larger than 2 so that a superposed magnetic field may be generated on the incident axis of the charged-particle beam and the trajectory of the charged-particle beam may be controlled by the superposed magnetic field.

摘要： A new cavity which is separate from a rf (radio frequency) accelerating cavity is provided on the orbit of charged particles in a ring-shaped accelerator, and an external oscillator and a coupled antenna which serve to excite a rf electromagnetic field in the separate cavity are provided. Using the external oscillator and the coupled antenna, a deflection mode which has electric field components in the direction of the central orbit of the charged particles and in which a magnetic field in a direction perpendicular to the plane of the central orbit develops on the central orbit of the charged particles is excited in a beam duct part of the separate cavity through which the charged particles pass. The resonant frequency of the deflection mode is set at integral times that of a fundamental rf mode in the rf accelerating cavity, and the phase relationship between the rf fields of the rf accelerating cavity and the separate cavity is so held that, when the rf electric field intensity of the rf accelerating cavity has a phase of zero, the rf magnetic field intensity of the separate cavity rises in phase.
