Energy deposition studies for synchrotron radiation (SR) in the FCC-ee arcs in FLUKA
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 the electronics.

The system can measure TID and High-Energy Hadron and Thermal Neutron fluences, thanks to the Floating-Gate dosimeter and SRAMs embedded in the sensor mezzanine. Its radiation qualification is complicated both by its low-power and wireless architecture, but also by the unavailability of CHARM. An alternative and specific qualification methodology is needed.

Ground-based research for radiation protection in space travel
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.

Radiation tolerance of EPDM O-rings used at CERN: recent results
Synthetic EPDM elastomers are used in vacuum seals throughout CERN, including Beam Intercepting Devices, and seal-lifetime may be severely limited by radiation exposure. Different varieties of EPDM O-rings are available on the market, and recent experiments carried out by R2M at CERN show that there is considerable variation in their radiation tolerance. The results of mechanical and structural investigations will be presented.
Speaker: Matteo Ferrari (CERN) -
31
Radiation damage studies on lubricants
Tribological studies are fundamental to mechanical design and especially relevant in the high radiation environment around beam-intercepting devices. Although only few studies exist, the effect of radiation on organic compounds is highly variable and lubricant resistance can be the determining factor in equipment lifetime. Preliminary examination of first lubricant samples irradiated in gamma and mixed fields will be shown.

New NEAR irradiation station at n_TOF: design, implementation and first results
A new irradiation station has been built and commissioned at CERN's n_ToF facility, enabling new types of neutron-dominated irradiations and activation studies. The irradiation setup is radiation tolerant and is handled remotely to reduce dose to operators. Pilot irradiations of commercial lubricants and O-ring materials started in July 2021, and recently concluded successfully, in compliance with RP requirements.

IFMIF-DONES facility: a key accelerator neutron source for the design of DEMO
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.
