## Abstract A numerical study is made of the dynamics of Ar^+^ ions collected by a cylindrical Langmuir probe at medium He buffer gas pressure. The numerical model is based on a combination of PIC simulation for the ion component and fluid description for the electrons using the Boltzmann relation.
We have carried out Monte Carlo simulation of the motion of Ar + ions in the space charge sheath surrounding a cylindrical Langmuir probe. The ion currents to the probe have been calculated from these simulations and the percentages of ions crossing the sheath boundary that are collected by the prob
