Title: Structure of the charged sheath at the plasma-charged body boundary

Abstract

Based on a hydrodynamic plasma model that incorporates the inertia and temperatures of the plasma components, we have analytically and numerically solved the problem on the structure of the charged sheath at the plasma-charged body boundary. We formulate a criterion for the existence of a stationary charged sheath at the plasma-charged body boundary for both charge signs and with allowance made for the inertia and temperatures of the charged plasma components. We determine the minimum and maximum electric potentials and densities of the charged plasma components in the sheath. We show that the charge profile in the sheath can form a double-layer structure in which the ion-depleted and electron-depleted sublayers are adjacent to the plasma and the charged body, respectively, with the electric potential in the sheath remaining monotonic.
