Activities for Isotope Sample Production and Radiation Effect Tests at JULIC/COSY Jülich

At the Forschungszentrum Jülich (FZJ) the intermediate energy cyclotron JULIC, used as injector of the Cooler Synchrotron (COSY) and COSY itself, have been enabled to perform low to medium current irradiations. Main task is to support the FZJ radionuclide research programme of INM-5. Target holders of the INM-5 were implemented to the external target station of JULIC to obtain reliable irradiations with 45 MeV protons and 76 MeV deuterons for nuclear reaction cross section measurements and medical radionuclide production. For testing of radiation effects, displacement damage DD and single event effects SEE, with energetic protons for electronics used in space and accelerators the beam can be extracted to a dedicated test stand, e.g. used by Fraunhofer INT. To provide these possibilities up to 2.5 GeV as well one external beamline of the cooler synchrotron COSY will be equipped with a new irradiation station and adaption for the dosimetry systems are done. Different dosimetry systems (PTW Farmer® chambers, Bragg Peak chambers, Gafchromic® dosimetry films) are available to monitor and control the ongoing irradiation. This report briefly summarizes the relevant technical activities.
