The Marburg Ion-Beam Therapy Centre (MIT), located in Marburg, Germany, is in clinical operation since 2015. MIT is designed for precision cancer treatment using beams of protons or carbon nuclei, employing the raster scanning technique. The accelerator facility consists of a linac-synchrotron combination, developed by Siemens Healthcare/Danfysik, that was in a state of permanent stand-by upon purchase.

In 2005 a high temperature vacuum furnace was put into operation at the Institute for Nuclear Physics at the Technische Universität Darmstadt. It has been designed for firing pure Niobium at temperatures of up to 1870 C. Until now several Nb cavities have been heat treated at 850 C with a proven record of success. The current focus of research in improving the superconductive characteristics of accelerator cavities is on new materials such as Nb3Sn or NbN or on the doping of Nb surfaces with nitrogen, so called N2-Doping. The surface preparations generally take place at temperatures of not more than 1000 C. To study phenomena that occur at higher temperatures, like the formation of delta-phase NbN at 1300 to 1700 C, it is planned to refurbish the UHV furnace and use it for corresponding studies. We will report on the design of a new annealing pot and a sample holder and give a review on our first experiences with the upgraded furnace.
