Design and Optimization of the Beamstrahlung Beamline Vacuum Separation Window for the FCC-ee: Mitigating High-Energy γ-ray Impact / Christensen, Kenneth Bisgaard (The University of Manchester (GB))
This study presents the design and optimization of the Beamstrahlung Beamline Vacuum Separation Window for the Future Circular Collider electron-positron collider (FCC-ee), focusing on mitigating the impact of high-energy γ-ray photons. The window is subjected to challenging operational conditions, including vacuum pressure from the beamline side and a 1.2 ATM overpressure in the beamstrahlung dump, while also being exposed to significant thermal loads due to high-energy γ-ray photon bombardment.

70 years at the high-energy frontier with the CERN accelerator complex / Brüning, Oliver (CERN) ; Klein, Max (Liverpool U.) ; Myers, Stephen (CERN) ; Rossi, Lucio (Milan Bicocca U. ; LASA, Segrate)
Over the first 70 years of its existence, CERN has created an impressive portfolio of accelerators, many of which are still in operation today. The ‘jewel in the crown’ of the complex is certainly the 27-km tunnel and its infrastructure, built approximately 100 m underground between the Jura mountains and Lake Geneva on the French–Swiss border. [...]

Highly uniform silicon nanopatterning with deep-ultraviolet femtosecond pulses / Granados, Eduardo (CERN) ; Martinez-Calderon, Miguel (CERN) ; Groussin, Baptiste (CERN) ; Colombier, Jean Philippe (Lab. Hubert Curien, St. Etienne) ; Santiago, Ibon
Abstract The prospect of employing nanophotonic methods for controlling photon–electron interactions has ignited substantial interest within the particle accelerator community. Silicon-based integrated dielectric laser acceleration (DLA) has emerged as a viable option by leveraging localized photonic effects to emit, accelerate, and measure electron bunches using exclusively light. [...]

First Thomson scattering results from AWAKE’s helicon plasma source / Stollberg, C (Ecole Polytechnique, Lausanne) ; Guittienne, Ph (Ecole Polytechnique, Lausanne) ; Karimov, R (Ecole Polytechnique, Lausanne) ; Sublet, A (CERN) ; Furno, I (Ecole Polytechnique, Lausanne) ; Vincent, B (Ecole Polytechnique, Lausanne) ; Andrebe, Y (Ecole Polytechnique, Lausanne) ; Buttenschön, B (Greifswald, Max Planck Inst.)
We present the first results of electron density and temperature measurements obtained from Thomson scattering at the helicon plasma source (HPS) for the AWAKE project. These measurements are compared to simulation results from a 1D power and particle balance model (PPM), confirming that the plasma can be fully sustained by collisional power dissipation. [...]

Exploring the potential of resonance islands and bent crystals for a slow extraction from circular hadron accelerators / Veres, D.E. (CERN) ; Giovannozzi, M. (CERN) ; Franchetti, G. (Darmstadt, GSI)
New developments in accelerator physics have broadened the set of available techniques for manipulating charged-particle beams. Adiabatic trapping and transport of beam in resonance islands has been studied and successfully implemented at the CERN Proton Synchrotron to perform multiturn extraction. [...]
