Abstract

We have developed a 180° deflection toroidal analyzer for photo- and Auger electron diffraction. Due to the simultaneous registration of the wide range of polar angles in a given azimuth of the sample, measurements of photo- and Auger electron intensities over π steradians can be performed rapidly by azimuthal rotation of the sample. In order to obtain the Auger electron diffraction data, it was necessary to measure the accurate energy distribution on the detector. Thus, we have constructed a newly designed input-lens-system, so that the energy resolution of the analyzer has been improved. Using this analyzer, some examples of full-solid-angle Auger electron diffraction (AED) patterns measured in short acquisition times were presented. The AED patterns obtained were compared with theoretical ones calculated by the multiple-scattering scheme.
