Measurement of two dimensional velocity distributions of ions in a plasma chamber

Abstract:

The paper reports on non-invasive measurements of the two-dimensional velocity distributions of species in a plasma. In this report, the technique of recovering velocity information from measurements of Doppler shifts in the absorption frequency of a species is applied to the lower concentrations of ions in a reactive ion etching chamber. In addition, the B-X electronic system of N2 ions is probed and the Doppler profile is built. By combining several profiles, it became possible to invert to...
