Abstract

The transport properties of O− ions in water vapour drifting in DC fields were obtained by using the Monte Carlo simulation technique with the scattering cross section sets assessed on the basis of Denpoh and Nanbu’s technique and available experimental data. A swarm method is applied to determine
recommended cross section set. For the first time in this work we present the transport parameters for the conditions of low to moderate reduced electric fields E/N (N is gas density) accounting for the effect of non-conservative collisions. The data are applicable in the limit of low pressures where cluster formation does not affect the transport or may be applied at higher pressures together with a model of cluster formation kinetics.
