Abstract
Over the past decades we have seen enormous progress in fusion science as well as in various fusion technology fields. On the basis of these results, obtained in joint European reactor JET and in smaller machines, a construction of even a bigger reactor - ITER is planned. In parallel to its construction, the accompanying research program will still be executed in order to support the future operation of the reactor. Recently, the Slovenian researchers have successfully joined the common European research efforts in the field and EU supports their projects in the 6th Framework program. Our proposed investigations are included in a broader project on interaction of vibrationally excited hydrogen molecules with materials relevant for fusion and on properties of edge plasmas. We intend to modify the existing plasma device in order to make it applicable for fusion relevant research and to construct a new smaller device for investigations of hydrogen plasma with negative ions and to develop some new and improve the existing diagnostic equipment and methods. We will continue the study of the formation of plasma potential in plasma in front of a negative and a positive wall, by which a reactor wall, a divertor plate, or a probe surface is ment.
The overall subject is relevant for fusion machines like tokamaks on the one hand and negative ion sources on the other hand. The data obtained in this project would constitute valuable input in the corresponding modeling codes. From the investigations of the formation of nonlinear potential structures some new fundamental contributions for the development and use of experimentally measured data analysis are expected. The study of the anode double layer in the anode plasma could contribute some interesting findings to the newly emerging field of self-organizing systems research.
