Abstract

A future circular collider (FCC) with a center-of-mass energy of 100 TeV and a circumference of around 100 km, or an energy upgrade of the LHC (HE-LHC) to 27 TeV require bending magnets providing 16 T in a 50-mm aperture. Several development programs for these magnets, based on Nb3Sn technology, are being pursued in Europe and in the U.S. In these programs, cos-theta, block-type, common-coil, and canted-cos-theta magnets are explored; first model magnets are under manufacture; limits on conductor stress levels are studied; and a conductor with enhanced characteristics is developed. This paper summarizes and discusses the status, plans, and preliminary results of these programs.

Abstract

A next step of energy increase of hadron colliders beyond the LHC requires high-field superconducting magnets capable of providing a dipolar field in the range of 16 T in a 50-mm aperture with accelerator quality. These characteristics could meet the requirements for an upgrade of the LHC to twice the present beam energy or for a 100-TeV center of mass energy future circular collider. This paper summarizes the activities and plans for the development of these magnets, in particular within the 16 T Magnet Technology Program, the WP5 of the EuroCirCol, and the U.S. Magnet Development Program.

6. Validation of the Protection Scheme for the HL-LHC MBRD Magnet by Simulations and Prototype Tests

Abstract

The High-Luminosity upgrade of the Large Hadron Collider (LHC) (Todesco et al., 2021) foresees the replacement of the magnets around the interaction points of the ATLAS and CMS experiments at CERN. One of the new magnets is the separation-recombination dipole, also called Main Bending Recombination Dipole (MBRD)(Caiffi et al., 2021), (Levi et al., 2022) in the D2 cryomagnet assembly. It consists of a cosine-theta, double aperture with same polarity, winded with a Nb-Ti Rutherford cable, with a central field of 4.5 T and a magnetic length of 7.78 m, which generates an integrated magnetic field of 35 Tm, inside of a bore 105 mm in diameter. The magnet is a collaborative effort with a design and production follow up by INFN Genova, production by ASG Superconductors, cold mass assembly and test by CERN. One 1.6 m short model and a full-scale prototype have been fully tested, while four series magnets and 2 spares are currently being built. To cope with a stored energy of 2.2 MJ in the single layer magnet, the quench heater technology has been optimized and dimensioned to limit the hot spot temperature to 300 K. This paper will describe the design choices for the tested protection scheme and the results obtained by the test, including failure case studies. The data will be compared to the STEAM-LEDET (Ravaioli et al., 2016) simulations and used to further validate the modeling parameters. With the obtained results from the tests and from modeling, the protection scheme has been validated and will be applied in the series magnet production.

Abstract

The Future Circular Collider in hadron-hadron configuration (FCC-hh) is one of the main options for the post-LHC era of particle accelerator. The project led by CERN aims to build a 100 km-long collider with 100 TeV of center-of-mass energy, using bending dipoles able to achieve a bore field $>$14 T. The Istituto Nazionale di Fisica Nucleare (INFN) and CERN are collaborating to construct a Nb$_{3}$Sn cos-theta dipole model, to increase the R&D efforts for high-field superconducting magnets technology, according to the updated European Strategy for Particle Physics. Here we give an update on the intense design activity, and we report the results of the first winding trials performed with a dummy conductor, to experimentally validate the magnet design and start the iterative process to optimize the manufacturing method. The results of the first winding tests are shown in the paper, focusing on the impact of the coiling procedure on the mechanical behavior of the unreacted Nb$_{3}$Sn Rutherford cable.
