1.5.3
The magnetic pre-sheath
In most situations when EIRENE is applied to plasma surface interaction studies the ionplasma flow velocity Vi is predominantly parallel to a B field: V∥,i ≈ |Vi |, and it is this parallel ion flow velocity, which is usually available from CFD plasma simulations, via boundary
conditions specified for the momentum balance equation at the entrance of the magnetic presheath (M P ) rather than at the entrance of the electrostatic sheath S.
The sheath model of EIRENE then is supplemented by a model PRE-SHEATH for the transition of currents and Vi,M P to Vi,S , i.e. in particular to derive the currents jπ,S and flow
components Vπ,i,S entering the electrostatic sheath from jM P and Vi,M P
