note = "Funding Information: The upgraded TOMAS device is well-suited to study W7-X relevant wall conditioning methods. First results of three main wall conditioning techniques have been demonstrated. The outgassing rates of the dominating species during the baking procedure can be described by adopting known models. The operational range and main GD parameters for W7-X – prototype anode have been defined. The behaviour of impurities release during the GDC is briefly described but, nevertheless, it needs more detailed analysis. In case of ECWC, the difference between H2 and He conditionings was analysed and the presence of different water release processes with H2 as working gas has been shown. The origin of this type of impuritiesoseuiwllrbctuseed idn futiure.
