Abstract
Collisionless and quasi‐neutral hydrodynamic model of plasmas consisting of electrons and several species of ions are investigated. When two species of ions are considered, the hyperbolicity of the system of transport equations obtained in the quasi‐neutrality limit leads to a restriction on the magnitude of the admissible relative velocities.

An electron kinetic code is used to simulate lonqitudinal transport and recycling near the neutralizer plate in a divertor plasma. In addition to the standard features, such as e-• and e-i Coulomb collisions, transport, ion motion, and a self-consistent eleCtric field, the code now accounts for ioni
The neutrals in a tokamak divertor in the so-called "detached" mode of operation may be in a kinetic regime (long mean free path) in some regions and in a fluid regime (short mean free path) elsewhere. For example, a kinetic description is necessary in the thin ionization front, while the cold neutr
