Abstract The High Luminosity Large Hadron Collider (HL-LHC) is the new flagship project of CERN. First endorsed in 2013 and approved 2016, HL-LHC an upgrade accelerator aiming to increase by a factor ten statistics LHC collisions at horizon 2035–2040. relies on cutting edge technologies: among them, large aperture superconducting magnets will replace present hardware allow smaller beam size two interaction points (IPs). involves construction about 150 six different types: quadrupole triplet,...
A key challenge for a future circular collider (FCC) with centre-of-mass energy of 100 TeV and circumference in the range km is development high-field superconducting accelerator magnets, capable providing 16 T dipolar field quality 50 mm aperture. This paper summarizes strategy actions being undertaken framework FCC Magnet Technology Program Work Package 5 EuroCirCol.
A next step of energy increase hadron colliders beyond the LHC requires high-field superconducting magnets capable providing a dipolar field in range 16 T 50-mm aperture with accelerator quality. These characteristics could meet requirements for an upgrade to twice present beam or 100-TeV center mass future circular collider. This paper summarizes activities and plans development these magnets, inand U.S. Magnet Development Program.

An integrated design approach is used at CERN for the and optimization of superconducting accelerator magnets, with ROXIE program package as key tool. The layout coil ends has proven in most cases to be limiting factor magnets' quench performance. objectives end are therefore minimize mechanical stress on cables, optimize multipole content, limit peak field enhancement. This paper introduces a new based differential geometry methods that allows geometrical cos n/spl theta/ ends.
The electrical integrity of superconducting magnets that go through a resistive transition (quench) is an important consideration in magnet design. Numerical quench simulation leads to coupled thermodynamic and electromagnetic problem, due the mutual dependence material parameters. While many tools treat field problem one independently, more recent developments adopt strongly approach 3-D finite-element environment. We introduce computationally efficient weak electromagnetic-thermodynamic...
