Plasma-wall transition in weakly collisional plasmas
نویسندگان
چکیده
This paper reviews some theoretical and computational aspects of plasma-wall interactions, in particidar the formation of sheaths. Some fundamental residts are derived analytically using a simple fluid model, and are subsequently tested with kinetic simulations. The various regions composing the plasma-wall transition (Debye sheath, colUsional and magnetic presheaths) are discussed in details.

Vlasov simulations of plasma-wall interactions in an argon-helium plasma
Introduction The plasma-wall transition problem is relevant to most areas of plasma physics. In magnetically confined fusion devices, charged particles in the plasma edge can erode the wall, thus reducing the lifetime of the components facing the plasma. Energetic particles hitting the wall may deteriorate the quality of the plasma confinement, because high-Z impurities are released from the wa...
متن کاملComplete spectrum of kinetic eigenmodes for plasma oscillations in a weakly collisional plasma.
Kinetic eigenmodes of plasma oscillations in a weakly collisional plasma, described by a collision operator of the Fokker-Planck type, are obtained in closed form for initial-value as well as for boundary-value problems. These eigenmodes, which are smooth and compose a complete discrete spectrum, play the same role for weakly collisional plasmas as the Case-Van Kampen modes do for collisionless...
متن کاملFluid description of collisional current filamentation instability of a weakly ionized plasma in the presence of magnetic field
In this paper, the collisional filamentation instability of an electron beam-weakly magnetized and ionized plasma has been investigated in the presence of background plasma, using the fluid description. By describing the equilibrium configuration in the presence of binary collision terms between charged and neutral particles and using the local approximation method, the dispersion relation (DR)...
متن کاملNumerical simulation of plasma-wall interactions in weakly collisional plasmas
Eulerian Vlasov codes, which solve the kinetic equation on a fixed phase-space grid, have become increasingly popular in the fusion plasma physics community. Their main advantage is the lack of random statistical noise inherent to particle-in-cell (PIC) calculations. Although they do require a somewhat larger computational effort compared to their PIC counterparts, Eulerian codes are now able t...
متن کاملVlasov simulations of plasma-wall interactions in a magnetized and weakly collisional plasma
A Vlasov code is used to model the transition region between an equilibrium plasma and an absorbing wall in the presence of a tilted magnetic field, for the case of a weakly collisional plasma mfp i, where mfp is the ion-neutral mean-free path and i is the ion Larmor radius . The phase space structure of the plasma-wall transition is analyzed in detail and theoretical estimates of the magnetic ...
