    Abstract: A spherical aberration corrector is offered which permits a correction of deviation of the circularity of at least one of an image and a diffraction pattern and a correction of on-axis aberrations to be carried out independently. The spherical aberration corrector (100) is for use with a charged particle beam instrument (1) for obtaining the image and the diffraction pattern and has a hexapole field generating portion (110) for producing plural stages of hexapole fields, an octopole field superimposing portion (120) for superimposing an octopole on at least one of the plural stages of hexapole fields to correct deviation of the circularity of at least one of the image and diffraction pattern, and a deflection portion (130) for deflecting a charged particle beam.

    Abstract: A deceleration apparatus capable of decelerating a short spot beam or a tall ribbon beam is disclosed. In either case, effects tending to degrade the shape of the beam profile are controlled. Caps to shield the ion beam from external potentials are provided. Electrodes whose position and potentials are adjustable are provided, on opposite sides of the beam, to ensure that the shape of the decelerating and deflecting electric fields does not significantly deviate from the optimum shape, even in the presence of the significant space-charge of high current low-energy beams of heavy ions.

    Abstract: A particle source in which energy selection occurs by sending a beam of electrically charged particles eccentrically through a lens so that energy dispersion will occur in an image formed by the lens. By projecting this image onto a slit in an energy selecting diaphragm, it is possible to allow only particles in a limited portion of the energy spectrum to pass. Consequently, the passed beam will have a reduced energy spread. The energy dispersed spot is imaged on the slit by a deflector. When positioning the energy dispersed spot on the slit, central beam is deflected from the axis to such an extent that it is stopped by the energy selecting diaphragm. Hereby reflections and contamination resulting from this beam in the region after the diaphragm are avoided. Also electron-electron interaction resulting from the electrons from the central beam interacting with the energy filtered beam in the area of deflector is avoided.
