      abstract     = {Vortices in electron beams can manifest several types of
                      topological phenomena, such as the formation of exotic
                      structures or interactions with topologically structured
                      electromagnetic fields. For instance, the wave function of
                      an electron beam can acquire a phase vortex upon propagating
                      through a magnetic monopole. In practice, this provides a
                      convenient method for generating electron vortex beams, yet
                      it is very limited by the structural integrity of devices
                      used for such purposes. Here, we show how an electric field
                      must be structured in order to achieve a similar effect. We
                      find that closed but not exact electric fields can produce
                      electron vortex beams. We proceed by fabricating a
                      versatile, robust, and near-obstruction-free device that is
                      designed to approximately produce such fields and we
                      systematically study their influence on incoming electron
                      beams. With such a single device, electron vortex beams that
                      are defined by a wide range of topological charges can be
                      produced by means of a slight variation of an applied
                      voltage. For this reason, this device is expected to be
                      important in applications that rely on the sequential
                      generation and manipulation of different types of electron
                      vortices.},
