Glow discharges with electrostatic confinement of fast electrons, of which the best known example are hollow cathode discharges (HCDs), are widely used for diverse technological applications such as light sources, high-power electric switches and electric propulsion, amongst others. In a recent topical review published in JPhysD [1] V I Kolobov and A S Metel — collaborators from the US and Russia — present a unified treatment of glow discharges with electrostatic confinement of fast electrons, outlining common physics between different types of such discharges.
