A dynamic beam window for coupling accelerator and reactor core in an ADS / Caspers, Fritz (CERN) ; Mueller, Alex C. (ACM Consult GmbH, Mainz)
During the many fruitful discussions and presentations at this EUCARD2-workshop we all were once more reminded of the respective technical short comings of the two solutions bringing an intense proton-beam on a molten-lead spallation target housed inside a fuel-loaded reactor. These are namely the window-less target solution where the accelerator is completely unprotected from accidentally back-streaming target material or the window solution with it’s inherent danger of catastrophic failure.

High-Field Design Concept for Second Interaction Region of the Electron-Ion Collider / Gamage, Bamunuvita (Jefferson Lab) ; Arbelaez, Diego (LBNL, Berkeley) ; Aschenauer, Elke (Brookhaven) ; Berg, J (Brookhaven) ; Ent, Rolf (Jefferson Lab) ; Ferracin, Paolo (LBNL, Berkeley) ; Morozov, Vasiliy (ORNL, Oak Ridge (main)) ; Rajput-Ghoshal, Renuka (Jefferson Lab) ; Sabbi, GianLuca (LBNL, Berkeley) ; Satogata, Todd (Jefferson Lab) et al.
Efficient realization of the scientific potential of the Electron Ion Collider (EIC) calls for addition of a future second Interaction Region (2nd IR) and a detector in the RHIC IR8 region after the EIC project completion. The second IR and detector are needed to independently cross-check the results of the first detector, and to provide measurements with complementary acceptance. [...]

Brussels (main)) ; Shields, William (U. Brussels (main)) et al.
Monte Carlo simulations are required to evaluate beam losses and secondary radiation accurately in particle accelerators and beamlines. Detailed CAD geometries are critical to account for a realistic distribution of material masses but increase the model complexity and often lead to code duplication. [...]

The Electron-Positron Future Circular Collider (FCC-ee) / Zimmermann, Frank (CERN) ; Benedikt, Michael (CERN) ; Oide, Katsunobu (Geneva U. ; KEK, Tsukuba) ; Raubenheimer, Tor (SLAC)
The Future Circular electron-positron Collider (FCC-ee) is aimed at studying the Z and W bosons, the Higgs, and top quark with extremely high luminosity and good energy efficiency. Responding to a request from the 2020 Update of the European Strategy for Particle Physics, in 2021 the CERN Council has launched the FCC Feasibility Study to examine the detailed implementation of such a collider.

Activation of the IBA Proteus One Proton Therapy Beamline Using BDSIM and FISPACT-II / Ramoisiaux, Eliott (U. Brussels (main)) ; Gnacadja, Eustache (U. Brussels (main)) ; Hernalsteens, Cédric (U. Brussels (main) ; CERN) ; Pauly, Nicolas (U. Brussels (main)) ; Tesse, Robin (U. Brussels (main)) ; Vanwelde, Marion (U. Brussels (main))
Cyclotron-based proton therapy systems generate large fluxes of secondary particles due to the beam interactions with the beamline elements, with the energy degrader being the dominant source. Compact systems exacerbate these challenges for concrete shielding and beamline element activation. [...]
