Monte-Carlo Simulations for the shielding-design of the next generation GSI facility

Introduction Shielding calculations for the GSI future project [1] have been performed using the radiation transport code FLUKA [2, 3]. FLUKA is capable of simulating hadronic and electro-magnetic interactions of particles with matter. Here the task is to attenuate radiation generated inside experimental areas or accelerators to a dose rate not larger than 0.5μSv/h at outer walls and to estimate the limiting values for the activation of soil and ground water [4]. The materials used for shielding are concrete [5] and iron for parts of beam dumps. The basic layout for the SIS100/200, the area for experiments with compressed hadronic matter, and the area for the anti-proton target and the corresponding separator have been simulated.
