Abstract
An arrangement and a method for imaging, examining and processing a sample using electrons. The arrangement comprises an electron microscope for providing electrons, a chamber with a sample holder on which a sample is positionable such that it can be imaged, examined and processed using the electrons. A system for magnetic field compensation in at least one spatial direction, including a compensation coil, wherein a wall of the chamber has an accommodation area, in sections thereof, for a portion of the compensation coil. Generally, only the chamber in which the sample is arranged is considered as a compensation volume. It suffice to reduce the compensation volume to the sensitive region of the electron microscope, since it is in the chamber, shortly following a final focusing and filtering, where the electron beam is most sensitive in terms of image quality when subjected to external electromagnetic interference.
