Abstract

Intensity distribution in a diffraction pattern of the electron diffraction at a filament depends to a great extent on its diameter. This is used for the determination of the filament diameter with an accuracy better than 2%. The described method is suitable e.g. for the determination of the local filament diameter in an electron biprism. Therefore the non-uniform diameter of filaments used in an electron biprism presents no difficulties in the interpretation of diffraction and interference patterns.
