Depletion of hydrogenoid atoms from the carbonized layer in Tore Supra
The wall production of deuterium and hydrogen during a helium glow discharge of 1.6 x 1.0 E5 has been studied after 100 deuterium plasma shots in Tore Supra. After a transient, the desorption followed a t(-1) time behaviour for the deuterium and a t(-1/2) behaviour for the hydrogen. The results are discussed in terms of ion-induced release for the deuterium and a diffusion-limited mechanism for the hydrogen. The values obtained for the different parameters are in good agreement with the relevant data from the literature.
