N2 - A self-consistent description (performed by means of the B2-EIRENE code package) of a hydrogen plasma including electrons, ions and neutral background gas is used to investigate the processes and plasma behavior under conditions expected in MAGNUM-PSI. Several cases varying in gas-puffing, pumping rate, and plasma parameters are simulated. In all cases a detached plasma regime is achieved. The plasma d. increases considerably for higher neutral pressures up to (1-5) * 1014 cm-3. The particle flux to the target is .apprx.1024 m-2 s-1 and the plasma heat flux is .apprx.10 MW m-2. The latter is significantly reduced in front of the target due to electron and ion cooling resulting from ionization and dissocn. of H2 mols., and charge exchange/elastic collisions. Under the conditions of investigation, the losses due to mol. activated recombination are dominant compared with 3-body recombination of at. ions. [on SciFinder (R)]
