Numerical study and mitigation strategies of radiation damage of the Super-FRS Ion Catcher setup — •Tommaso Piazza1,3, Daler Amanbayev2,3, Davide Bortot1, Timo Dickel2,3, Wolfgang Plass2,3, Ekaterina Kozlova2, and Alexey Sokolov2 — 1Politecnico di Milano, Italy — 2GSI Darmstadt — 3JLU Giessen
At the Super-FRS, experiments with exotic nuclei produced by the projectile fragmentation or fission of a high energy (up to 1.5 GeV/u) primary beam will be performed. The interaction between the secondary beam and the components along the beamline, such as the degrader and the collimators, produces a complex secondary radiation field. Irradiation represents a challenging condition, by means of both physical damage and degradation of the electrical performance, for the supply and controllers' electronics of the Super-FRS Ion Catcher.
The present research firstly addresses the main interaction mechanisms between radiation and electronics. The most relevant quantities to evaluate are the absorbed dose and the fast neutron fluence, which is connected to structural damage. Secondly, simulations are performed with FLUKA software reproducing a simplified geometry of the beamline, to assess the composition of the radiation field and the physical quantities of interest. The results are compared with relevant literature data to establish the risk of damage. The possible risk reduction solutions range from the relocation of the components to low radiation level areas to the design of a shielding device.
