Abstract :
Summary form only given, as follows. The Vlasov-Maxwell equations in the Lorentz gauge and in the quasi-electrostatic limit have been considered on ion time scales in 4-6 dimensions (including nu ), subject to certain boundary and volume conditions. The sheath physics near a Faraday shield has been studied under this formulation. Several Faraday shield configurations, including the Perkins, TFTR, and JET shields, have been studied, focusing on scenarios and conditions affecting metallic impurity generation.<>
