A discussion is given of the transition from the region where the ionization is dominant to the region where the space charge is important, for a collisionless model of a low-pressure arc discharge. As the relevant Poisson equation contains a very small parameter which multiplies the second order derivative, a singular perturbation formalism leads to an unambiguous definition of the plasma and the sheath regions, and to a precise reformulation of the Bohm criterion. The same formalism allows explicit calculations, on the basis of particular models, of the potential within the sheath and the plasma, and of the ion current to the wall. (auth)
