Abstract

Description

We have presented the experimental observation of the spatial structure of Molecular Assisted Recombination (MAR) including both dissociative recombination and mutual neutralization channels in the detached hydrogen plasma in the linear divertor plasma simulator, TPD-SheetIV. It is shown from the results of mass-analysis (H2+, H3+) that dissociative recombination is dominant in the center of the plasma over a range of low gas pressures. At the same time, it is observed that the mutual neutralization in MAR via H- ion formation, which is produced by dissociative electron attachment to H2(v), occurs in the periphery of the plasma where cold electrons (~1 eV) are found.
