/ Prioli, Marco (LASA, Segrate) ; Santini, Carlo (LASA, Segrate) ; Barna, Daniel (Wigner RCP, Budapest) ; Gusvitskii, Todor (Rome U.) ; Perini, Diego (CERN) ; Bianchi, E (INFN, Genoa) ; Felcini, Enrico (CNAO, Milan) ; De Matteis, Ernesto (LASA, Segrate) ; Toral, Fernando (Madrid, CIEMAT) ; Levi, Filippo (INFN, Genoa) et al.
Various initiatives in Europe have been launched to study superconducting magnets for a rotatable gantry suitable to deliver up to 430 MeV/u carbon ions for hadron therapy. Different technologies and layouts are being considered: the baseline solution is developed within the EuroSIG collaboration and consists of a strongly curved cos-$\theta$ dipole based on the classical NbTi superconductor.

SC magnet design - EM part I
/ Farinon, Stefania (speaker) (INFN e Universita Genova (IT))
After a brief recap of the derivation of field harmonics, this lecture delineates the process of creating multipoles with current lines, focusing particularly on dipoles and quadrupoles. The presentation covers the derivation of ideal dipolar and quadrupolar fields, as well as more realistic cases such as sector coils and canted cos-theta configurations..

Protecting the magnets in case of a quench is a challenge for the 16 T superconducting dipole magnets presently designed for the 100 TeV: Future Circular Collider (FCC). These magnets are driven to the foreseen technological limits in terms of critical current, mechanical strength and quench protection. [...]

The Development of MBRD Magnets, the Separation/Recombination Dipoles for the LHC High Luminosity Upgrade
/ Farinon, Stefania (INFN, Genoa) ; Angius, Silvano (ASG Supercond., Genova) ; Barutti, Alberto (ASG Supercond., Genova) ; Bersani, Andrea (INFN, Genoa) ; Bracco, Michela (Genoa U. ; INFN, Genoa) ; Caiffi, Barbara (INFN, Genoa) ; Fabbricatore, Pasquale (INFN, Genoa) ; Fiscarelli, Lucio (CERN) ; Foussat, Arnaud (CERN) ; Gagno, Andrea (Genoa U. ; INFN, Genoa) et al.
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.
