Econ., Karlsruhe) ; Bersani, Andrea (INFN, Genoa) ; Bracco, Michela (INFN, Genoa) ; Farinon, Stefania (INFN, Genoa) ; Foussat, Arnaud (CERN) ; Gagno, Andrea (INFN, Genoa) ; Levi, Filippo (INFN, Genoa) ; Mangiarotti, Franco (CERN) ; Ninet, Gaelle (CERN) et al.
The High-Luminosity upgrade of the Large Hadron Collider (LHC) (Todesco et al., 2021) foresees the replacement of the magnets around the interaction points of the ATLAS and CMS experiments at CERN. One of the new magnets is the separation-recombination dipole, also called Main Bending Recombination Dipole (MBRD)(Caiffi et al., 2021), (Levi et al., 2022) in the D2 cryomagnet assembly. [...]

The MBRD (Main Bending Recombination Dipole, or D2) is one of the magnets in the interaction region of the LHC that needs to be replaced in order to fulfill the requirements of the High-Luminosity upgrade. The magnetic field must be increased up to 4.5 T in an aperture with a diameter of 105 mm and a total length of about 8 m, to reach the target integrated field of 35 T$\cdot$m. [...]

Genoa) ; Mangiarotti, Franco (CERN) ; Pampaloni, Alessandra (INFN, Genoa) et al.
The recombination dipoles D2 (MBRD) for the luminosity upgrade of the Large Hadron Collider (LHC) are double aperture magnets to be placed on each side of ATLAS and CMS experiments, generating 4.5 T along a magnetic length of 7.78 m and a bore diameter of 105 mm. Its development plan foresees the construction of a short model 1.6 m long, followed by a prototype and by the series of 6 magnets. [...]

The recombination dipoles MBRD for the High Luminosity upgrade of the Large Hadron Collider (HL-LHC) at CERN are double-aperture superconducting magnets generating a central magnetic field of 4.5 T in a 105 mm diameter bore, directed in the same direction in both apertures. The integrated magnetic field is 35 T-m in a magnetic length of 7.78 m: with respect to the corresponding magnet presently installed in LHC, the aperture is larger, the length is smaller and the central field is higher.

The next upgrade for the Large Hadron Collider (LHC), called High-Luminosity LHC, has the aim of increasing the rate of collisions of the accelerator by a factor of ten. To achieve this goal, the dipole and quadrupole magnets before and after the interaction region of the ATLAS and CMS experiments will be replaced. [...]

The Main Bending Recombination Dipole (MBRD), or D2, is one of the magnets foreseen by the High-Luminosity upgrade of the Large Hadron Collider (LHC). D2 features a double aperture, Nb-Ti, cos $\theta$dipole, with a central field of 4.5 T for a length of 7.78 m, hence with an integrated magnetic field of 35 T$\cdot$m, in a 105 mm bore. [...]

As part of the high-luminosity upgrade of CERN LHC accelerator project, the National Institute of Nuclear Physics (INFN) in Genoa, Italy, has developed the MBRD separation-recombination dipole, also known as D2, whose function is to bring beams into collision before and after the interaction regions of the CMS and ATLAS experiments. It is a NbTi cos-theta double aperture dipole that generates a 4.5 T field in a 105 mm aperture, with a magnetic length of 7.78 m, and has the specific feature that the magnetic field in the two apertures is oriented in the same direction.
