    Abstract: The invention describes a corrector for the correction of chromatic aberrations in a particle lens, such as used in a SEM or a TEM. So as to reduce the stability demands on the power supplies of such a corrector, the energy with which the particle beam passes through the corrector is lower than the energy with which the beam passes through the lens to be corrected.

    Abstract: A system including co-axial focused ion beam and an electron beam allows for accurate processing with the FIB using images formed by the electron beam. In one embodiment, a deflector deflects the electron beam onto the axis of the ion beam and deflects secondary particles collected through the final lens toward a detector. In one embodiment, a positively biased final electrostatic lens focuses both beams using the same voltage to allow simultaneous or alternating FIB and SEM operation. In one embodiment, the landing energy of the electrons can be varied without changing the working distance.
