Electron vortex beams (EVB) were theoretically predicted in 2007 and first experimentally
created in 2010. Although they attracted attention of many researchers, their
investigation takes place almost solely in connection with transmission electron microscopes (TEM). On the other hand, although scanning electron microscopes (SEM) may provide some advantages for EVB applications, only little attention has been dedicated to them. Therefore, the aim of this work is to create electron vortices in SEM at energies of several keV.
