Description

The plasma sheath mechanisms are well-known in non-magnetised plasmas, but a model for a sheath in a tilted magnetic field does not exist. In this work, we present the development of a facility to study the sheath of RF plasmas in a tilted magnetic field. We aim at characterising the sheath by determining the potential, the electron and the ion temperatures and densities. To measure these parameters, a movable planar electrostatic probe will be combined with optical emission spectroscopy. In this contribution, first probe measurements in Ar discharges under 0.5T are discussed.
