Due to a planned intervention the CERN Document Server website will be read only (no new submission or restricted content) from Tuesday, June 29th at 13:30 CEST to Wednesday, June 30th at 9:30 CEST.
The website will be shortly unavailable at the beginning and at the end of the intervention.

Development and Fabrication of Nb$_3$Sn Rutherford Cable for the 11 T DS Dipole Demonstration Model / Barzi, E (Fermilab) ; Lombardo, V (Fermilab) ; Nobrega, F (Fermilab) ; Turrioni, D (Fermilab) ; Yamada, R (Fermilab) ; Zlobin, A V (Fermilab) ; Karppinen, M (CERN)
Fermilab and CERN started the development of 11 T Nb$_3$Sn dipoles 11 m long to replace a few regular LHC NbTi dipoles and free space for cold collimators in LHC dispersion suppression (DS) areas. An important step in the design of these magnets is the development of the high aspect ratio Nb$_3$Sn cable to achieve the nominal field of 11 T at the nominal LHC operating current of 11.85 kA with 20% margin.

Design and Fabrication of a Single-Aperture 11T Nb$_3$Sn Dipole Model for LHC Upgrades / Andreev, N (Fermilab) ; Apollinari, G (Fermilab) ; Barzi, E (Fermilab) ; Bossert, R (Fermilab) ; Nobrega, F (Fermilab) ; Novitski, I (Fermilab) ; Turrioni, D (Fermilab) ; Yamada, R (Fermilab) ; Zlobin, A V (Fermilab) ; Auchmann, B (CERN) et al.
The planned upgrade of the LHC collimation system includes additional collimators to be installed in the dispersion suppressor areas of points 2, 3 and 7. To provide the necessary longitudinal space for the collimators, a replacement of 8.33 T Nb-Ti LHC main dipoles with 11 T dipoles based on Nb3Sn superconductor compatible with the LHC lattice and main systems is being considered.

The Gamma Factory (GF) initiative proposes to use partially stripped ion (PSI) beams as drivers of a new type of high-intensity and high-energy (0.1–400 MeV) photon source. As part of the ongoing Physics Beyond Collider studies, initial beam tests were carried out in 2017 and 2018 at the SPS and LHC with partially stripped xenon and lead beams [...]

Achieving the targets of the High Luminosity LHC project requires the installation of new inner triplet magnet circuits for the final focusing of the particle beams on each side of the two main interaction points. Each of the four circuits will include six 150 mm aperture, 132.2 T/m gradient, Nb$_3$Sn quadrupole magnets to be installed in the LHC tunnel. [...]
