Assessing the origin of the LHC beam halo / Rakic, Milica (CERN ; Ecole Polytechnique, Lausanne) ; Hermes, Pascal (CERN) ; Redaelli, Stefano (CERN) ; Butti, Daniele (CERN) ; Mirarchi, Daniele (CERN) ; Roncarolo, Federico (CERN) ; Bartosik, Hannes (CERN) ; Hostettler, Michi (CERN) ; Kostoglou, Sofia (CERN) ; Seidel, Mike (PSI, Villigen)
Measurements of the transverse beam-halo population at large amplitudes in the Large Hadron Collider (LHC) provide crucial insights into the stored beam energy near the LHC collimators. These particles do not contribute significantly to the luminosity but their loss could impose limitations on accelerator performance through sudden loss spikes or even collimator damage in case of fast beam failures.

Space Charge in Circular Machines / Ferrario, Massimo (U. Rome La Sapienza (main) ; Frascati) ; Migliorati, Mauro (Frascati ; U. Rome La Sapienza (main)) ; Palumbo, Luigi (U. Rome La Sapienza (main) ; Frascati)
Space charge forces, which arise directly from the beam's charge distribution and include the influence of image charges and currents induced by interactions with a perfectly conducting, smooth pipe, are very important in high-intensity, low-energy accelerators. [...]

Numerical application of the mode matching technique to the longitudinal impedance computation in particle accelerators / Biancacci, N (CERN) ; Passarelli, A (INFN, Naples)
The accurate knowledge of the beam coupling impedance in particle accelerators is important in order to address potential impedance-driven instabilities and for planning machine upgrades. While simple models exist for various components (e.g., beam pipes, step transitions, and collimators), they are often insufficient to correctly describe the overall machine impedance with the necessary precision.
