Professor Josef Zweck is head of the electron microscopy group at the University of Regensburg's physics faculty (Germany). An important branch of his work specializes in imaging of intrinsic magnetic and electrostatic fields and their in-situ manipulation by specialized specimen holders.

so that overall there was a decline in interest in in situ experiments. This interest has been revived comparatively recently by the availability of the high-voltage electron microscope (HVEM) which, by comparison with kV machines, provides an ap- proximately three-fold increase in working volume around the specimen and a four-Cited by:   In-situ high-resolution electron microscopy is a modern and powerful technique in materials research, physics, and chemistry.

In-situ techniques are hardly treated in textbooks of electron microscopy. Thus, there is a need to collect the present knowledge about the techniques and achievements of in-situ electron microscopy in one book.

Since. alloys, studied by in situ straining experiments in a high-voltage electron microscope, is compared at room temperature and at high temperatures. In contrast to room temperature, the dislocations move viscously at high temperatures, which is explained by diffusion processes in the dislocation cores.

An environmental cell has been designed for in situ oxidation experiments in the high-voltage electron microscope. The gas around the specimen is separated from the microscope vacuum by two apertures on both sides and a differential pumping system operating between the inner and outer apertures.

A scanning transmission electron microscope has been converted into a high-voltage scanning electron microscope (HVSEM) with a large specimen chamber. By imaging with high-energy electrons ( keV) and detecting backscattered electrons, voids in metal lines can be viewed through passivation by: A new method for conducting in situ observations of experiments undergoing irradiation in a high voltage electron microscope (HVEM) is.

By using a SEM, we achieve the resolution of the electron probe in the few-nm range, which is of great advantage as the surface roughness of the polished accelerating structures is in the same scale.

A new method for conducting in situ observations of experiments undergoing irradiation in a high voltage electron microscope (HVEM) is proposed. Intensity profile of a focused electron beam in HVEM introduces an atomic displacement gradient in the vicinity of the beam, which generates distribution of point defect concentration and enhances defect diffusion in matrix.
