Abstract
We present numerical modelling results and first experimental steps on an experiment aiming at guiding electrons in an AC quadrupole guide. In the proposed setup, electrons originating from a sharp tungsten field emission source will be focused by means of a suitable electron-lens system into a linear Paul-trap operating at microwave frequencies (Fig. 1). The control over the electrons' motional degrees of freedom gained in this way would allow e.g. for interference experiments with guided electrons or the deterministic interaction of two counterpropagating electrons.
