The HEARTS EU Project and Its Initial Results on Fragmented High-Energy Heavy-Ion Single-Event Effects Testing
/ García Alía, Rubén (CERN) ; Waets, Andreas (CERN ; Zurich U.) ; Coronetti, Andrea (CERN ; IES, Montpellier) ; Bilko, Kacper (CERN ; Jean Monnet U.) ; Delrieux, Marc (CERN) ; Emriskova, Natalia (CERN) ; Esposito, Luigi (CERN) ; Fraser, Matthew (CERN) ; Johnson, Eliott (CERN) ; Klimek, Karolina (CERN) et al.
We perform single-event effect (SEE) tests with well-characterized fully fragmented (i.e., beyond Bragg peak) high-energy heavy-ion beams and compare the results with those expected from conventional, mono-linear energy transfer (mono-LET) measurements, showing a satisfactory level of agreement between the two. This compliance paves the way for the exploitation of simulation tools for accurately quantifying the ion fragmentation impact on SEE rates for both ground-level testing conditions and space galactic cosmic-ray (GCR) environments, with electronics operating behind significant thicknesses of shielding.

Development of a ReBCO Non/Metal-Insulated 40 T Solenoid for a Muon Collider
/ Bordini, B (CERN) ; Accettura, C (CERN) ; Bertarelli, A (CERN) ; Bottura, L (CERN) ; Dudarev, A (CERN) ; Hafiz, M A (CERN) ; Kolehmainen, A (CERN) ; Mulder, T (CERN) ; Rinaldoni, D (CERN) ; Sanda, F (CERN) et al.
In the quest to explore the fundamental properties of particles at the energy frontier, the International Muon Collider Collaboration (IMCC) has made significant progress in the conceptual design study of a Muon Collider (MC). Central to this effort is the development of the various MC's magnet systems, particularly the Ultra-High-Field (UHF) solenoids needed for the MC final cooling stage. [...]

The PSI Positron Production (P3 or P-cubed) experiment is a e+ source and capture system with the potential to increase by an order of magnitude the state-of-the-art e+ yield normalized to the drive linac energy, a highly desirable goal for future colliders. The experiment is framed in the FCC-ee injector study and will be hosted at SwissFEL, located at the Paul Scherrer Institute in Switzerland. [...]

Development, Fabrication & Test of the Round, Multi-Layer REBCO Cables of the Cold Powering Systems of the HL-LHC
/ Barth, C (CERN) ; Saba, A (CERN) ; Leclercq, Y (CERN) ; Ballarino, A (CERN)
The magnets of the High Luminosity Upgrade of the Large Hadron collider (HL-LHC) will be electrically connected through Cold Powering Systems incorporating superconducting, 100 kA class, power transmission lines to direct current power converters in service galleries. These transmission lines or ‘Superconducting Links’ are based on multi-circuit magnesium di-boride ($\text{MgB}_{2}$) cables in 74.5–120 m long flexible cryostats. [...]

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.

Complex Impedance of the LHC Main Dipole Magnet in the Presence of Artificial Short Circuits
/ Janitschke, M (CERN ; U. Rostock) ; Ravaioli, E (CERN) ; Verweij, A P (CERN) ; Willering, G (CERN) ; van Rienen, U (U. Rostock)
Interturn short circuits inside the coil-winding pack of superconducting magnets can lead to severe damage to the magnet during a quench or fast current ramps. Investigating their impact and finding ways to detect these nonconformities could save considerable run-time of an accelerator. [...]

Characteristic Timescales for the Operation of HTS CICCs in Compact Fusion Reactors
/ Breschi, Marco (Bologna U.) ; Savoldi, Laura (Polytech. Turin ; INFN, Genoa ; CERN) ; Cavallucci, Lorenzo (Bologna U. ; INFN, Bologna) ; Bottura, Luca (CERN)
In this work we address the shift from Low Temperature Superconductor (LTS) to High Temperature Superconductor (HTS) magnets presently occurring in the development of machines for controlled thermonuclear fusion with magnetic confinement. This shift implies several new challenges, which cannot be ignored in the design and modelling of the future HTS magnets. [...]
