Wall conditioning plays a key role to assist the discharge start-up and to achieve high-performance plasma scenarios, especially after machine vents and impurity events. This article describes the conditioning systems of the Divertor Test Tokamak (DTT) by focusing on the design of the baking and glow discharge conditioning systems. A general overview of the current design is presented by discussing the main working parameters and the features of each technology under investigation. The integration into the machine is also discussed, by considering the main limitations and interface with other subsystems, particularly with the diagnostic and the pumping system.
