At the Forschungszentrum Karlsruhe, Germany, a compact gyrotron system has been established in order to investigate technological applications in the field of high temperature materials processing by means of millimeter wave radiation. For more detailed investigations in the field of sintering of various functional and structural ceramics a specific dilatometer setup has been designed and build into the mm-wave oven of the gyrotron system. System design and experimental results will be presented.
