The Prospect for Accelerator Superconducting Magnets: HL-LHC and Beyond

Superconducting Magnets for High Energy Physics Accelerators are entering a new era. The successful operation of the LHC in the last decade has marked the summit of the Nb-Ti technology exploitation initiated by the Tevatron. Now, after two decades of development, Nb3Sn technology for accelerators is becoming mature and the construction of the high luminosity LHC (HL-LHC) magnets will be the most tangible sign of the new phase, with magnets that will operate well beyond the symbolic threshold of 10 T. In addition, 30 years after its discovery, the high temperature superconductors (HTSs) for accelerator magnets are under development and test, to understand if these materials can enable the 20 T range for next accelerator/colliders foreseen after 2030. The paper reviews the main issues and the criticalities of the magnets’ development for the next future project, HL-LHC, and gives the prospect for the design and technological effort that is underway in magnet technology for the energy Frontier (FCC/HE-LHC).

Energy Physics

In view of the preparation for a post-LHC collider, the high-energy physics (HEP) community started from 2010 to discuss various options, including the use of HTS for very high field dipoles. Therefore, a small program was set in Europe aiming at exploring the possibility of using HTS for accelerator quality magnets. Based on various EU funded programs, though at modest levels, has enabled the European community of accelerator magnets to start getting experience in HTS and addressing a few issues. The program was based on use of REBCO tapes to form 10 kA Roebel cables, to be used to wind small dipoles of 30-40 mm aperture in the 5 T range. The dipoles are designed to be later inserted in a background dipole field (in Nb3Sn), to reach eventually a field level in the 16-20 T range, beyond the reach of LTS. The program is currently underway: more than 1 km tape of high performance (Je &gt; 500 A/mm2 at 20 T, 4.2 K has been manufactured and characterized, various 30 m long Roebel cables have been assembled and validated up to 13 kA, a few dipoles have been wound and tested, reaching at present 4.5 T in stand-alone (while a dipole made from race track coils with no-bore exceeded 5 T using stacked tape cable) and a test in a background field is being organized.

Axiomatic Quantum Field Theory

In a previous work a novel parametrization was proposed for the [Formula: see text] and [Formula: see text] total cross-sections. Here, results are presented for the updated analysis with taking into account the recent data from accelerator experiments as well as from cosmic ray measurements. The analytic parametrizations suggested within axiomatic quantum field theory (AQFT) provide the quantitative description of energy dependence of global scattering observables with robust values of fit parameters. Based on the fit results the estimations are derived for the total cross-section and the [Formula: see text] parameter in elastic [Formula: see text] scattering at various [Formula: see text] up to energy frontier [Formula: see text] PeV which can be useful for present and future hadron colliders as well as for cosmic ray measurements at ultra-high energies.
