5.5.1 Selecting the Gun Mode

The microscope can operate in different gun modes:

§
Imaging Gun Mode In Imaging gun mode, the temperature of the Schottky emitter and the extraction voltage are re-
duced in comparison to the Analytic gun mode. This leads to a reduction of the energy spread of
the primary electrons.
Imaging gun mode is suitable for lower probe currents. Imaging gun mode is especially useful at
low kV to reduce chromatic aberration and to achieve a better resolution.
