Practical Aspects of CBED Specimen Preparation and Operation in the TEM

2 Practical Aspects of CBED Specimen Preparation and Operation in the TEM [Pg.52]

The normal procedures for obtaining CBED patterns are described in [21-23] and here are summarized in the following steps  [Pg.52]

Insert the selected area diffraction aperture, focus the image and switch the diffraction mode. Thus, a conventional SADP is obtained as starting point for the next operations. [Pg.52]

Focus the pattern by using the intermediate lens and C2 lens control and remove the selected area and objective apertures. Return to the image mode. [Pg.52]

Insert a small C2 condenser aperture and focus the shadow image of the aperture with the objective lens the image will then go out of focus. [Pg.52]
