Toward axial channeling deployment at the Large Hadron Collider / Mirarchi, D (CERN) ; D'Andrea, M (CERN) ; Mazzolari, A (INFN, Ferrara) ; Redaelli, S (CERN)
Efficient steering of particle beams in accelerators by means of bent crystals has been pursued over the last decades. Recent achievements in their operational deployment at CERN has resulted in a renewed interest in their exploitation for advanced accelerator and high energy physics concepts. [...]

Design and optimizations of electrostatic low energy intense beam transport for H$^{-}$ ion source in LINAC4 at CERN / Jakhar, Niketan (Nehru U.) ; Kumar, Sarvesh (IUAC, New Delhi) ; Thakur, Chandan (Nehru U.) ; Kashyap, Sandeep (Amity U., Sch. Eng. Tech. ; Indian Inst. Tech., New Delhi) ; Sharma, Jyotsna (Delhi Tech. U.) ; Kashyap, Manish K (Nehru U.) ; Lombardi, Alessandra (CERN)
Abstract The electrostatic low energy beam transport (ELEBT) is used to handle low energy and intense beams from ion sources. It is preferred over magnetostatic low energy beam transport (MLEBT) for many reasons such as compactness, no space charge compensation and no transverse phase space coupling, more beam current handling capacity and less emittance growth as well as beam losses.

Possible crystal applications for FCC and beyond / Zimmermann, Frank (CERN)
This article first describes the status and plans for the proposed Future Circular Collider (FCC), and then surveys possible crystal and channeling applications for the FCC. The latter range from crystal-based positron production, over crystalline undulators, to crystal collimation. [...]

Magnetic design of downstream scanning magnets for a novel hadrontherapy gantry / Felcini, Enrico (Unlisted, IT) ; Schwarz, Philip (CERN) ; Pullia, Marco (Unlisted, IT)
Hadrontherapy utilizes accelerated ion beams to deliver precise and effective cancer treatments, depositing energy at specific depths while sparing healthy tissues. Gantries are large rotating structures that direct beams at various angles around the patient, improving dose conformity to tumors and the robustness of the treatment plan while minimizing radiation exposure to surrounding organs.

Dechanneling Population at Extreme Crystal Bending with 6.5 TeV Proton Beam / Rossi, Roberto (CERN) ; Mirarchi, Daniele (CERN) ; Redaelli, Stefano (CERN) ; Scandale, Walter (CERN)
Beam measurements with bent crystals, installed in the Large Hadron Collider to assist multistage collimation system, provided information on hadron interactions with crystals in the multi–TeV energy range. In particular, the dechanneling population was observed through scans of deflected halo with collimators. [...]

Magnetic Field and Temperature Scaling of the Critical Current of REBCO Tapes / Succi, G (CERN ; Southampton U.) ; Ballarino, A (CERN) ; Hopkins, S C (CERN) ; Barth, C (CERN) ; Yang, Y (Southampton U.)
High temperature superconductors (HTS) in the form of REBCO (RE1Ba2Cu3O7-δ) coated conductor tapes have undergone, in recent years, major improvement of their transport current properties in high magnetic fields and at liquid helium temperature. The modelling of coils and other applications using REBCO tapes requires accurate characterization and precise knowledge of their properties. [...]
