Abstrakt: The ultrahighvacuum Scanning Electron Microscope has been built using the column of an old prototype (later produced as Tesla BS 350), some spare parts for BS 350 and new components, including computer controlled electronics. The whole vacuum system was extensively reconstructed, too. The Schottky cathode was introduced into the microscope instead of the original cold field emission gun. The advantage of this system includes a high current density, higher stability and lower vacuum demands at comparable performance as regards the resolution. Therefore it is possible to practice surface analysis with Auger electrons at a high resolution. The microscope was also adapted to the operation with slow and very slow electrons, again at high resolution, so that these two methods can be in situ compared.
