The optical properties of thermionic triode electron guns, governed largely by the wehnelt, are studied in depth with the aid of a simple model. A unified theory of the beam energy characteristics—total current, brightness and energy distribution

A detailed theoretical analysis of the possibility of obtaining the information on lattice distortions from high-resolution images of crystal structures is presented. The analysis is based on the calculation of the image intensity of a deformed cryst

Metal-containing diamond-like carbon hard coatings (Me-DLC) consist of nanometre size metallic particles, embedded into an amorphous hydrocarbon matrix. Their mechanical, tribological and electrical properties are strongly influenced by the size and

Metal containing amorphous hydrocarbon films consist of nanometer size metallic particles in a hydrogen-carbon matrix. Scanning tunneling microscopy (STM) of Au and Pt containing amorphous C:H-films was performed in order to determine particle size-

Metal containing amorphous hydrogenated carbon films are protective coating materials with very low friction coefficients, high hardness and wear resistance, combined with an adjustable electrical conductivity. The structure of these films, consistin

An off-axis hologram is obtained by recording the interference pattern resulting from the superposition of the object wave and a slightly tilted reference wave. The phase distribution of the object wave is a function of several parameters such as the

In an electron microscope equipped with a field emission gun, highly magnified micrographs can be taken within short exposure times by reducing the distance between the object and the effective crossover down to 7 μm. Due to the dependence of the Se

The aberration coefficients of electron guns are determined from experimental shadow curves. For this purpose the curves are mathematically described by parametric equations using the ray inclination at the cathode as a parameter. Since the shape of

Emittance diagrams of electron guns were measured by means of a shadow method and compared with computed diagrams given in the literature. The calculated ray characteristics and particularly the paraxial ray data could be confirmed, but not the data
