Characterization of Fragmented Ultra-high Energy Heavy Ion Beam and its Effects on Electronics Single Event Effect Testing

Ultra-high energy (> 5 GeV/n) heavy ion beams exhibit different properties when compared to standard and high energy ion beams. Most notably, fragmentation is a fundamental feature of the beam that may have important implications for electronics testing given the ultra-high energies, and hence ranges, preserved by the fragments. In this work, both the primary lead ion beam, available in the CERN North Area, and its fragments are characterized by means of solid-state detectors. This input is later used to improve the measurements of Single Event Effects in commercial components with this beam. Moreover, the energy deposition distribution in the solid-state detectors is compared to that obtained with Monte Carlo simulations.
