MEASUREMENT OF ACTIVATION INDUCED BY AN ARGON BEAM IN A COPPER TARGET AT THE SIS18*

Several laboratories in the world have started or plan to build new powerful ion accelerators. These facilities promise to provide very valuable tools for experiments in fundamental nuclear physics, physics of high energy density in matter and for medical applications as well. One of the most important problems that have to be solved during the design stage is the radiation protection of the accelerator. Due to the complexity it is hardly possible to obtain reliable radionuclide production data for accelerator structure materials from radiation transport codes. Thus, the experimental data which can be measured at the presently existing facilities (SIS-18, Ganil) are necessary for the evaluation of the induced levels of radioactivity around intense heavy ion accelerators. Results of the measurement of activation induced by Argon beam with energies of E = 300, 500, 800 MeV/u in the copper target are presented in this paper
