Glow discharge plays an important role in modern technology. It is an important example of a strongly non-uniform, non-equilibrium plasma, consisting of several parts with strongly different plasma parameters, which have to be matched. Electron energy distributions are typically non-Maxwellian, the system is highly non-linear and a multitude of atomic processes play a role. Basic discharge phenomena are described. In order to get a better insight into the physics of the glow discharge, only special types of glow discharges are discussed. Firstly, only dc discharges with cold cathode are considered, and discharges with hot cathode and ac-driven discharges are disregarded. Secondly, the simplest possible geometry (i.e. plane electrodes with a large diameter compared to the electrode distance) is chosen. Thirdly, only discharges in atomic gases and vapours are discussed. In order to be specific and at the same time cover important applications, discharges in He and Ar are considered.
