The Inner Triplet String Facility for HL-LHC: Design and Planning
/ Bajko, Marta (CERN) ; Bertolasi, Stefano (CERN) ; Bertone, Caterina (CERN) ; Blanchard, Sebastien (CERN) ; Bozzini, Davide (CERN) ; Brüning, Oliver (CERN) ; Cruikshank, Paul (CERN) ; De Luca, Davide (CERN) ; Dos Santos, Nuno (CERN) ; Dragoni, Francesco (CERN) et al.
In the framework of the HL-LHC project, full-scale integration and operational tests of the superconducting magnet chain, from the inner triplet quadrupoles up to the first separation/recombination dipole, are planned in conditions as similar as possible to the final set-up in the LHC tunnel. The IT String includes all of the required systems for operation at nominal conditions, such as vacuum, cryogenics, warm and cold powering equipment, and protection systems. [...]

Mechanical Structure for the PSI Canted-Cosine-Theta (CCT) Magnet Program
/ Montenero, Giuseppe (PSI, Villigen) ; Auchmann, Bernhard (CERN) ; Brouwer, Lucas (LBL, Berkeley) ; Calzolaio, Ciro (PSI, Villigen) ; Caspi, Shlomo (LBL, Berkeley) ; Rolando, Gabriella (PSI, Villigen) ; Sanfilippo, Stephane (PSI, Villigen)
Abstract: The Canted-Cosine-Theta (CCT) technology has the potential, by its intrinsic stress-management, to lower coil stresses in high-field accelerator magnets. This is especially relevant for Nb3Sn magnets, which may be subject to irreversible degradation if the coil stresses exceed critical values. [...]

Electromechanical Design of a 16-T CCT Twin-Aperture Dipole for FCC
/ Auchmann, Bernhard (CERN) ; Brouwer, Lucas (LBL, Berkeley) ; Caspi, Shlomo (LBL, Berkeley) ; Gao, Jiani (PSI, Villigen) ; Montenero, Giuseppe (PSI, Villigen) ; Negrazus, Marco (PSI, Villigen) ; Rolando, Gabriella (CERN) ; Sanfilippo, Stéphane (PSI, Villigen)
Canted-cosine-theta (CCT) technology has been studied for its suitability for a future-circular-collider (FCC) main dipole in terms of magnetic and mechanical performance, electrothermal protectability, as well as efficiency. In this paper, we present lessons learnt from our search for efficient CCT solutions by means of two-dimensional (2-D) magnetic and mechanical simulations, discuss the 3-D periodic mechanical model, as well as 3-D electromagnetic analysis of the end regions.

Design of 4 Tm Forward Dipoles for the FCC-hh Detector Magnet System
/ Mentink, Matthias (CERN) ; Pais Da Silva, Helder (CERN) ; Dudarev, Alexey (CERN) ; Rolando, Gabriella (CERN) ; Cure, Benoit (CERN) ; Gaddi, Andrea (CERN) ; Klyukhin, Vyacheslav (CERN) ; Gerwig, Hubert (CERN) ; Wagner, Udo (CERN) ; Ten Kate, Herman (CERN)
The 4 T, 10 m free bore twin Solenoid with 4 Tm forward dipoles is discussed with an emphasis on the forward dipoles. This assembly, a possible detector magnet layout for the future circular collider for hadron-hadron physics, combines a 4 T axial magnetic field at the interaction point in the center of the twin Solenoid with off-axis magnetic fields generated by the two forward dipoles for the purpose of providing bending power to all particles emanating from the interaction point.

An aggressive low-mass and high-stress design of a very large detector magnet assembly for the Future Circular Collider (FCC-hh), consisting of a “twin solenoid” and two dipoles, is presented. The twin solenoid features two concentric solenoids. [...]

Iron-free detector magnet options for the future circular collider
/ Mentink, Matthias (CERN) ; Dudarev, Alexey (CERN) ; Pais Da Silva, Helder Filipe (CERN) ; Rolando, Gabriella (CERN) ; Cure, Benoit (CERN) ; Gaddi, Andrea (CERN) ; Klyukhin, Slava (Lomonosov Moscow State U.) ; Gerwig, Hubert (CERN) ; Wagner, Udo (CERN) ; Ten Kate, Herman (CERN)
In this paper, several iron-free solenoid-based designs of a detector magnet for the future circular collider for hadron-hadron collisions (FCC-hh) are presented. The detector magnet designs for FCC-hh aim to provide bending power for particles over a wide pseudorapidity range (0 ≤ jηj ≤ 4). [...]

Fast Dump of the ATLAS Toroids

The toroidal magnet system of the ATLAS Detector at CERN consists of a Barrel Toroid (BT) and two End Cap Toroids (ECT-A and ECT-C). Each toroid is built up from eight racetrack coils wound with an aluminum stabilized NbTi conductor and indirectly cooled by forced flow liquid helium. [...]
