Characterization of the first wall of TEXTOR with respect to hydrogen recycling

  • 1. Institut fuer Plasmaphysik der Kernforschungsanlage Juelich GmbH, Association EURATOM-KFA, 5170 Juelich, Federal Republic of Germany

Description

The recycling constant R/sub c/ = D/2sigmak/sub r/ of the wall (D = diffusivity, 2sigmak/sub r/ = surface release rate constant of hydrogen) is an essential parameter for the understanding of the hydrogen recycling phenomena in fusion devices. It has been measured in situ in TEXTOR, using the wall pump and release effect. The method is described and data are presented in the temperature range of 150--300 0C for surfaces prepared by different conditioning techniques. The values are compared to available literature data from other tokamaks and from laboratory experiments
