Abstract
An analytical model taking into account the plasma cooling due to localized hydrogen recycling is proposed to interpret the conditions of the MARFE on set above a critical plasma density in TEXTOR-94. Results of numerical mode ling confirm that under conditions of a good plasma contact with the inner wall this mechanism of the MARFE triggering is more important than the usua lly considered cooling instability on impurity radiation.
