SR represents a major loss source in high energy lepton colliders, such as the FCC-ee. At a beam energy of 182.5GeV, its spectrum makes it penetrate well beyond the vacuum chamber walls. In order to optimize its containment, dedicated absorbers are envisaged. Furthermore, energy deposition studies were performed to develop a shielding layout in the tunnel with the aim of reducing the impact on...

Space radiation is generally acknowledged as the main health risk for human exploration of the Solar system. Beyond Low-Earth Orbit (BLEO) missions expose crews to increasingly high fluxes of cosmic rays, including protons and heavy ions. The high uncertainty on the biological effect of the extraterrestrial radiation makes it difficult to design countermeasures. Flight experiments have...
