    摘要: A particle-optical apparatus comprising:
    - A first source, for generating a first irradiating beam along a first axis;
    - A second source, for generating a second irradiating beam along a second axis that intersects the first axis at a beam intersection point, the first and second axes defining a beam plane,
    - A stage assembly for positioning a sample in the vicinity of the beam intersection point, provided with:

    - A sample table to which the sample can be mounted;
    - A set of actuators, arranged so as to effect translation of the sample table along directions substantially parallel to an X-axis perpendicular to the beam plane, a Y-axis parallel to the beam plane, and a Z-axis parallel to the beam plane, said X-axis, Y-axis and Z-axis being mutually orthogonal and passing through the beam intersection point,

    wherein the set of actuators is further arranged to effect:
    - rotation of the sample table about a rotation axis substantially parallel to the Z-axis, and;
    - rotation of the sample table about a flip axis substantially perpendicular to the Z-axis,

    whereby the flip axis can itself be rotated about the rotation axis.
