Abstract
Strong electron emission from a plasma or a solid surface is the basis of many applications such as high-power switching or intense electron beam generation. The electron emission in pseudospark geometries, from the interior of a hollow cathode and from the outer cathode surface, is discussed. These types of emission are compared with other emission methods by taking into account the electron current density, the spatial and the energy distribution, the beam quality, and the mechanisms, which allow each process to be controlled. A combination of different types of emitters may be the best solution for efficient power switching and for intense electron beam production. As examples, ferroelectric emitters in pseudospark-like switches and in electron beam sources are described.
