The close co-operation between Charité and HZB permits joint interdisciplinary research. Irradiations with either a sharp, well focused or a broad beam, either in vacuum or in air are possible. In addition, a 60Co-source for gamma-irradiations is available. Experiments now comprise dosimetry, detector comparisons, ambulant mouse irradiations, including class I gene-modified mice. Furthermore, radiation hardness tests on detectors, CCD-cameras and other electronics are performed. In order to improve the beam diagnosis between the 2 MV injector Tandetron and the cyclotron a harp has been installed, leading to new beam line calculations for the injection line. The accelerator operation for therapy as well as on-going experiments and results will be presented.
