N2 - A geometrically simple wire chamber has been built, consisting of a brass tube with a 20 µm wire in its centerline. An analysis of avalanche signals allowed us to determine the position and the spread, due to diffusion of the cloud of positive ions, as a function of time. It was confirmed that the shape of signals from proportional wire chambers can be accurately reconstructed in terms of the linear relation between ion drift velocity (w) and the electric field strength (E): w = µE, where µ is the mobility of ions. In fact, the ion mobility is measurable with this simple tube.
