Description
The Future Circular Collider-hadron-hadron (FCC-hh) project is envisioned as the successor to the Large Hadron Collider (LHC) at CERN (European Organization for Nuclear Research). The proposed particle accelerator, with a center-of-mass energy up to 100 TeV, will be housed in a tunnel approximately 100 km in circumference, representing a major leap forward in the exploration of fundamental forces and particles. A key component for the success of the project is the development of high-field dipole magnets capable of steering high-energy particle beams with precision and stability. In this context, the INFN (Istituto Nazionale di Fisica Nucleare) is involved with the FalconD (Future Accelerator post-LHC Cos$\theta$ Optimized Nb$_3$Sn Dipole) project, which focuses on the design and construction of a 12 T Nb$_3$Sn single-aperture cos$\theta$ dipole magnet. The prototype will demonstrate the feasibility of achieving the required magnetic field strength and test innovative manufacturing and assembly techniques. A distinguishing feature of the FalconD magnet is the use of the bladder and key (B$\&$K) assembly process, providing an innovative solution to the mechanical and operational challenges posed by high-field magnets in future accelerators. As a crucial step toward full-scale production, a mechanical mockup of the magnet’s straight section was constructed, as described in the Technical Design Report (TDR) published in 2021. This mockup aims to provide valuable insights into the mechanical behavior, assembly process, and cooling of the magnet under realistic conditions. In this contribution, we present the results of the mockup assembly and the corresponding experimental analysis of stress, measured using strain gauge technology. These experimental data will be compared with the results from the Finite Element Method (FEM) model to validate the theoretical predictions and optimize the magnet design for future applications.
