Abstract
The transient characteristics of a plane Langmuir probe for the case of an equilibrium distribution of the plasma particles were obtained by integration of the equations of motion of test particles. The conditions in which the transient characteristic has two peaks were determined. The first peak is due to ions whose initial velocity is directed towards the probe, and the second to ions whose initial velocity is directed away from the probe. The effect of electron relaxation on the leading edge of the probe current pulse was investigated. A relation connecting the plasma ion temperature with the lag of the probe current maximum is obtained.
