/ Wozniak, M (CERN) ; Devred, A (CERN) ; Ferriere, R (CERN) ; Haziot, A (CERN) ; Mangiarotti, F J (CERN) ; Kirby, G (CERN) ; Pentella, M (CERN) ; Petrone, C (CERN) ; Ravaioli, E (CERN) ; Verweij, A (CERN)
The Fusillo project at CERN aims to design and build a demonstrator magnet with multi-harmonic corrected fields in a 90°, curved, Canted-Cosine-Theta magnet. Two subscale magnets are built with 30° bending, about 1/30 of the demonstrator conductor length, and increased current to reach coil stresses equivalent to those of the demonstrator. [...]

Conceptual Design of BOND: A 14 T Dipole for FCC-Hh
/ Perez, Juan Carlos (CERN) ; Bellini, Gloria (CERN) ; Mora, Elena Fernandez (CERN) ; Ferradas Troitino, Jose (CERN) ; Haziot, Ariel (CERN) ; Izquierdo Bermudez, Susana (CERN) ; Todesco, Ezio (CERN)
High Field Nb$_{3}$Sn superconducting magnets are a core technology to increase the collision energy of particle accelerators beyond that of the Large Hadron Collider (LHC). In the framework of the conceptual design of a Future Circular Collider (FCC), or an energy upgrade of the LHC, different magnet layouts are being considered within the so-called High Field Magnet program.

Result of Powering and Field Measurements on the GaToroid Demonstrator
/ Bottura, L (CERN) ; Breschi, M (CERN) ; Haziot, A (Bologna U.) ; Lehtinen, T (CERN) ; Liebsch, M (CERN) ; Mangiarotti, F J (CERN) ; Pentella, M (CERN) ; Perez, J C (CERN) ; Petrone, C (CERN) ; Sedlak, K (Ecole Polytechnique, Lausanne) et al.
GaToroid is a novel idea of a steady-state, toroidal magnet that directs multiple charged particle beams for hadron or electron therapy without rotating parts or magnet ramping. GaToroid has the potential of conformal radiotherapy with a configuration that can be simpler and lighter than conventional rotating gantries, also offering FLASH capability well beyond what is presently possible.

Electromechanical Design of Nb3Sn Stress Managed Asymmetric Common-Coils
/ Araujo, D (PSI, Villigen) ; Auchmann, B (PSI, Villigen ; CERN) ; Brem, A (PSI, Villigen) ; Michlmayr, T (PSI, Villigen) ; Haziot, A (CERN) ; Ravaioli, E (CERN)
Stress-management of Nb3Sn coils offers a promising approach for high-field magnets by reducing conductor stress. The combination of stress-management and the common-coils magnet type simplifies manufacturing processes, such as utilizing the coil former in reaction and impregnation tooling. [...]

Performance of a HL-LHC Nb$_3$Sn Quadrupole Magnet in the 100–200 MPa Range of Azimuthal Stress
/ Mangiarotti, F J (CERN) ; Izquierdo Bermudez, S (CERN) ; Devred, A (CERN) ; Diaz Vez, R (CERN) ; Ferradas Troitino, J (CERN) ; Ferradas Troitino, S (CERN) ; Feuvrier, J (CERN) ; Guinchard, M (CERN) ; Haziot, A (CERN) ; Milanese, A (CERN) et al.
With the assembly and test results of four Nb$_\text{3}$Sn short-model quadrupoles (MQXFS) for the High Luminosity Upgrade of the CERN Large Hadron Collider (LHC), an optimum pre-load level was established for the construction of the full-length, series magnets. Successive MQXFS magnets were used as testbeds for potential changes (including pre-load fine tuning) to be implemented in the series, and to better understand the stress dependence of Nb$_\text{3}$Sn magnet performance.

Magnetic Design of a Compact GaToroid for Very High Energy Electron and Pre-Clinical Hadron Beams

GaToroid is a novel configuration of a beam delivery system for charged particles therapy based on a steady-state, axis-symmetric field configuration. The basic idea is to use fixed toroidal magnets, producing an axis-symmetric (or periodical axis-symmetric) field configuration that can bend beams from several directions onto the patient location.
