Ground-based research for radiation protection in space travel 1h
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 provided useful data on cosmic ray spectrum composition and dosimetry, but very limited information on late stochastic effects. Most of our knowledge on biological effects of space radiation comes from ground-based experiments at accelerators. We will review the activities in this field under way in the US (sponsored by NASA at the Brookhaven National Laboratory) and in Europe (supported by ESA at the SIS18 synchrotron at GSI) and the impact of this research on the missions to the Moon and Mars. In particular, we will show that the current dose limits for BLEO missions are inadequate and do not allow International missions.

IFMIF-DONES facility: a key accelerator neutron source for the design of DEMO 1h
The International Fusion Materials Irradiation Facility Demo Oriented NEutron Source (IFMIF-DONES) will be a novel research infrastructure for testing, validation and qualification of the materials to be used in a fusion reactor like DEMO. IFMIF DONES will mimic the conditions inside DEMO in terms of neutrons by the impact of a high-power deuteron beam onto a lithium target. Together with ITER (International Thermonuclear Experimental Reactor) it is the key facility to design DEMO. In view of the urgent need of data on materials and their durability, the construction of DONES (DEMO-Oriented Neutron Source) was decided. The IFMIF facility will consist of two accelerators delivering deuterons on the same neutron production target, whereas, DONES will consist of a single accelerator. Granada (Spain) was selected as the European city hosting the construction of the facility and the facility itself has been selected as ESFRI (European Strategy Forum on Research Infrastructures). In this talk an overview of the facility and its objectives will be carried out. Also, the complementary applications program will be briefly discussed.
