949. Design and construction of the first full-length prototype of the 11T dipole magnet for the High Luminosity LHC Project at CERN

Frederic Savary (CERN)

A1 - Superconducting Accelerator Magnets

Regular 15 minutes Oral Presentation

The luminosity upgrade of the Large Hadron Collider at CERN requires the installation of additional collimators in the dispersion suppressor regions of the accelerator. Amongst other things, the upgrade foresees the installation of one additional collimator on either side of IP 7 at the location of existing main dipoles that will be replaced by shorter and more powerful dipoles, and of one...

1160. Cold powering tests of the 2 meter Nb3Sn DS11T model magnets at CERN

A1 - Superconducting Accelerator Magnets

Regular 15 minutes Oral Presentation

For the upgrade of the LHC a few 15 meter Nb-Ti main dipole magnets are foreseen to be replaced by two 11 T Nb3Sn dipoles, 5.5 meter long each. A series of model magnets has been produced to verify the design choices that are important for the prototype and series production. A fourth and fifth 2 meter single aperture model and a second double aperture model coil were produced, assembled and...

1157. Design and test results of the Nb3Sn Canted-Cosine-Theta dipole magnet CCT4

A1 - Superconducting Accelerator Magnets

Regular 15 minutes Oral Presentation

The U.S. Magnet Development Program is developing Canted-Cosine-Theta (CCT) magnet technology for future high field accelerator magnets. The CCT concept prevents Lorentz force accumulation by placing turns within precision-machined grooves that are separated by ribs and a spar that intercept forces, sustainably reducing the stress in the conductor. With other non-stress managed coils, now...

914. Design and fabrication of a 15 T Nb3Sn accelerator dipole demonstrator

A1 - Superconducting Accelerator Magnets

Regular 15 minutes Oral Presentation

US Magnet Development Program (MDP) is developing a 15 T Nb3Sn dipole demonstrator for a post-LHC pp Collider. The magnet design is based on 60-mm aperture 4-layer shell-type coils, graded between the inner and outer layers to maximize the magnet performance. An innovative mechanical structure based on aluminum IC-clamps and a thick stainless steel skin was developed to preload brittle Nb3Sn...

539. Measurements of Persistent Current Effects in FNAL 11 T Nb3Sn Dipole Models

A1 - Superconducting Accelerator Magnets

Regular 15 minutes Oral Presentation

Fermilab, in collaboration with CERN, has developed a twin-aperture 11 T Nb3Sn dipole suitable for the high-luminosity LHC upgrade. During the 2012-2014, a 2-m long single-aperture dipole demonstrator and three 1-m long single-aperture dipole models were fabricated and tested at FNAL Vertical Magnet Test Facility. Collared coils from the two 1-m long models were then used to assemble the...

353. Electromechanical Design of a 16-T CCT Twin-Aperture Dipole for FCC

A1 - Superconducting Accelerator Magnets

Regular 15 minutes Oral Presentation

The CCT (Canted Cosine Theta) Technology has been studied for its suitability for an FCC main dipole in terms of magnetic and mechanical performance, electro-thermal protectability, as well as efficiency. In this paper we present lessons learnt from our search for efficient CCT solutions by means of 2-D magnetic and mechanical simulations, discuss the 3-D periodic mechanical model, as well as...
