Abstract : The dynamic behavior of a Langmuir probe immersed in a gaseous plasma is studied by using various measuring techniques. The delay in the current collection is investigated as a function of probe potential and plasma parameters and a qualitative theory based upon the motion of ions is presented. The capacitance of the probe sheath is calculated and compared with the measured values. In order to eliminate the influence of the stray probe capacitance on the measurements a shielded Langmuir probe was developed. (Author)
