The Helmholtz Zentrum Berlin and the Max Planck Society implement a new dedicated X ray beamline at the synchrotron light source BESSY II for the analysis of materials for the regenerative energy generation. The project is called EMIL, the Energy Materials In Situ Laboratory Berlin, [1] and the beamlines had to deliver x rays with a needed energy range from 80 eV up to 12000 eV. Therefore two undulators will be placed in a single straight section, for soft x rays an elliptical APPLE II device and for hard x rays a cryogenic in vacuum undulator. To determine adequate measures of the shielding of synchrotron radiation in the experimental hall we use the particle transport code FLUKA [2] [3]. We calculated the synchrotron radiation spectra for the cryogenic undulator with the code SPECTRA10 [4]. After modeling the modified section of the storage ring and the new beamlines we determined the thickness of the shielding walls of the hutches with the results of spectra sampling with FLUKA up to 30000 eV. The APPLE II undulator don t has to be considered for the hutch design because of its low energy synchrotron radiation 80 eV up to 2000 eV which is absorbed in the vacuum system. Additionally we considered the effects of the bremsstrahlung with FLUKA simulations
