Mobility of Ar$^{+}$ in CF$_4$

POSTER

Abstract

In this work we present a complete cross section set for Ar$^{+}$ in CF$_4$ where existing experimentally obtained data are selected and extrapolated. Monte Carlo simulation method is applied to accurately calculate transport parameters in hydrodynamic regime. We discuss new data for Ar$^{+}$ ions in CF$_4$ where flux and bulk values of reduced mobility are given as a function of E/N (E-electric field, N-gas density). We find that internally resonant exothermic dissociative charge transfer cross section for CF$_3^{+}$ production significantly increases zero field ion mobility with respect to the polarization limit.
