Description

The conditions for thermal instability caused by plasma-wall coupling are revisited after the implementation of a new 1D model for the wall energy and hydrogen species balance equations. It is found that the instability is plausible for wall properties close to those of carbon and is unlikely for the case of tungsten with no hydrogen traps. Typical growthrate of instability is of the order of inverse plasma particle and energy confinement times.
