Characteristics of monotonic sheaths near a wall with grazing magnetic incidence
Alessandro Geraldini, Robert J. Ewart, Stephan Brunner +1
We consider a magnetised plasma in contact with an absorbing planar wall, where the angle between the magnetic field and the wall is small, (in radians) and the syst…

On the importance of slow ions in the kinetic Bohm criterion
Alessandro Geraldini, Stephan Brunner
Between a plasma and a solid target lies a positively charged sheath of several Debye lengths in width, typically much smaller than the characteristic length scale …

Sheath constraints on turbulent magnetised plasmas
Alessandro Geraldini, Stephan Brunner, Felix I. Parra
A solid target in contact with a plasma charges (negatively) to reflect the more mobile species (electrons) and thus keep the bulk plasma quasineutral. To shield the bulk plasma fr…
