Аннотация:
The properties of carbon, with respect to its ability to absorb and release hydrogen, are reviewed and applied to the interpretation of density behaviour in Ohmic-, NBI- and ICRF-heated tokamak discharges. Based on the experimental observations, improvement of H-mode parameters in JET due to reduced hydrogen re-emission from the walls is predicted with a numerical model. The particle removal rates required for Q = 1 in JET are estimated.
