“…15. However, the importance of ion-induced detrapping has more recently been realized, and it has been shown to play an important role both in recycling and in other surface effects [49,77,78]. This process, whereby an incident ion desorbs an atom previously trapped in the solid lattice, has been studied in detail for the rare gases [72,79].…”

“…Experimentally it has been found that there are some sites from which the trapped atoms cannot easily be released and these have to be filled before ion-induced detrapping takes place [78,346]. The process can be described by an equation of the form: dt where N 2 is the number of sites which have high binding energies and Nj is the number with lower binding energies from which the atoms can be released.…”

Plasma-surface interactions in tokamaks

1979

View full text Add to dashboard Cite

A summary is given of the present status of research on plasma-surface interactions in tokamaks. Three groups of important interactions are considered: recycling of the principal ion species, usually hydrogen or deuterium; the release and effect of low-Z contaminants; and the release and effect of high-Z contaminants. In each case the basic physical processes are reviewed and the relevant data from particlebeam measurements are summarized. Emphasis is given to discussing the effect of the various surface interactions in present-day tokamak discharges and in future fusion reactors. Surface studies in tokamaks are reviewed and methods of controlling the surface interactions and their effects are considered.
