\def\Topic{First wall conditioning -- baking of the vessel and glow discharge influence on plasma performance} \def\Description{Plasma properties are degraded by flow of neutrals from the walls. Therefore, clear high temperature plasma can be achieved only with pure vessel walls. The cleanness of the walls can be influenced by baking of the tokamak chamber and also by glow discharge in hydrogen or helium. The goal is to find the best cleaning strategy to achieve the best plasma.} \def\MenuVesselConditioningStudies{ \begin{frame} \frametitle{\Topic} {\bf Goal:}\Description \begin{center} \GWincludegraphics{width=\textwidth}{Education/ExperimentMenu/VesselConditioning/GraphicBefore.png}\\ \GWincludegraphics{width=\textwidth}{Education/ExperimentMenu/VesselConditioning/GraphicAfter.png}\\ Evolution of main plasma parameters \\ upper) {\it before} and bottom) {\it after} vessel conditioning via baking. \end{center} \end{frame} }
