Container for components of a focused-ion-beam (FIB) system. FIB capabilities turn especially scanning electron microscopes into specimen preparation labs. FIB is a material preparation technique whereby portions of the sample are illuminated with a focused ion beam with controlled intensity intense enough and with sufficient ion momentum to remove material in a controllable manner. The fact that an electron microscope with FIB capabilities has needs a second gun with own relevant control circuits, focusing lenses, and other components, warrants an own base class to group these components and distinguish them from the lenses and components for creating and shaping the electron beam.
