The research establishment at Jülich concentrates on plasma and facing-components technology. The Tokamak TEXTOR was specially developed for this purpose, with the aim of determining the properties of the plasma edge and developing a facing-components system which can withstand the high heat and particle flux from the hot plasma for longer periods and is also compatible with the physical plasma requirements. ALT-II, the toroidal pump limiter, represents a significant development in this respect. The advantages are the low temperature, where the plasma appears detached from the limiters, that the thermal load is no longer primarily exerted on the limiters, but distributed evenly over the vessel as a whole and that the atomization of the facing-components material is considerably reduced. However, there were also longer confinement times for impurities which suggest that there were changes in the general confinement characteristics of this plasma configuration. The TEXTOR is well suited to further research into plasma and facing components interaction and the complex problems of materials selection, where it is used for integral tests and facing component experiments.
