Simulations and Performance Studies for the Forward Liquid Argon Experiment (FLArE) at the Forward Physics Facility / Vicenzi, Matteo (Brookhaven National Laboratory (US)) ; Bian, Jianming (University of California Irvine (US)) ; Diwan, Milind Vaman (Brookhaven National Laboratory (US)) ; Li, Yichen (Brookhaven National Laboratory (US)) ; Linden, Steven Keith (Brookhaven National Laboratory (US)) ; Salin, Olivier (Université Paris-Saclay (FR)) ; Wu, Wenjie (CERN) ; Xiao, Yiwen (University of California Irvine (US)) ; Yankelevich, Alejandro Jaime (University of California Irvine (US)) ; Yip, Kin (Brookhaven National Laboratory (US)) et al.
FLArE (Forward Liquid Argon Experiment) is a proposed Liquid Argon Time Projection Chamber (LArTPC) detector designed for very high-energy neutrinos and dark matter searches in the Forward Physics Facility (FPF), about $620~\mathrm{m}$ in the far-forward direction from the ATLAS interaction point at the Large Hadron Collider (LHC). This technical note describes the details of the simulation efforts performed for the design and optimization of the detector. [...]

FASER2: Detector Design and Performance / Salin, Olivier (Université Paris-Saclay (FR)) ; Barr, Alan (University of Oxford (GB)) ; McFayden, Josh (University of Sussex (GB)) ; Boyd, Jamie (CERN) ; Vranjes Milosavljevic, Marija (University of Belgrade (RS)) ; Vranjes, Nenad (University of Belgrade (RS)) ; D'Onofrio, Monica (University of Liverpool (GB)) ; Gwilliam, Carl (University of Liverpool (GB)) ; Anders, John Kenneth (University of Liverpool (GB)) ; Otono, Hidetoshi (Kyushu University (JP)) et al.
FASER2 is a proposed upgrade to the FASER experiment, and could be hosted in the Forward Physics Facility (FPF) suggested to be 620m to the west of the ATLAS interaction point, in the far-forward region of the LHC collisions. The upgrade involves a significantly enlarged volume compared to FASER, resulting in an increase in reach for various BSM signals of several orders of magnitude and allows sensitivity to models that were previously out of reach, such as Dark Higgs and Heavy Neutral Leptons.

Beam coupling impedance and collective effects for the Future Circular Lepton Collider / Carideo, Emanuela (Sapienza Universita e INFN, Roma I (IT))
Improving the accuracy of the impedance model of an accelerator is important in order to keep beam instabilities and power loss under control. This is particularly relevant in the context of the FCC−ee, a future electron−positron circular collider that requires very intense multi-bunch colliding beams with a very small transverse beam size at the collision points.

The ongoing feasibility study of the Future Circular Collider (FCC) comprises two distinct accelerators: a high-luminosity circular electron-positron collider known as FCC-ee and an energy-frontier hadron collider named FCC-hh. These two facilities are designed to take advantage of a common tunnel infrastructure. [...]

R&D; for positron sources at high-energy lepton colliders / Moortgat-Pick, G (Hamburg U. ; DESY) ; Formela, M (Hamburg U.) ; Hamann, N (Hamburg U.) ; Lengler, T (Dresden, Tech. U.) ; Lott, D (Dresden, Tech. U.) ; Loisch, G (Hamburg U.) ; Riemann, S (DESY) ; Sievers, P (CERN) ; Tenholt, C (DESY) ; Yakopov, G (DESY)
Positron Sources for high luminosity high-energy colliders are a challenge for all future lepton colliders as, for instance, the International Linear Collider (ILC) as well as new concepts as the HALHF collider design. In the talk new R&D; developments for the undulator-based positron source are discussed. [...]

Study of the Damage Potential of the FCC-ee Beams / Hjelle, Ingrid Midtbust
The beam characteristics of the Future Circular Collider electron-positron (FCC-ee) beam differ vastly from those of the Large Hadron Collider (LHC) beam and the High Luminosity LHC (HL-LHC) beam, presenting new challenges for assessing beam impact and damage potential [...]
