Since 1978, when the CELLO magnet was manufactured, superconducting detector magnets have been wound using NbTi based, Aluminum stabilized conductors. However, other choices are possible and Magnesium Diboride (MgB2) could be an attractive alternative. Magnets wound with MgB2 can be operated at relatively high temperature (10 to 20 K),...

The Superconducting Ion Gantry (SIG) project is the contribution from INFN (the Italian National Institute for Nuclear Physics) to the international SIGRUM project with the aim of exploring new technological solutions for the critical elements of a 430 MeV/u carbon ion gantry. The project includes the design and construction of a cos\theta 4 T...

The Deep Underground Neutrino Experiment (DUNE) at Fermilab is one the most challenging next-generation experiments in the field of neutrino physics. It will feature two detectors for a detailed study of neutrino oscillations using an unprecedentedly intense neutrino beam. The two detectors are a Near Detector located on the Fermilab site, 574...

The High-Luminosity upgrade of the Large Hadron Collider (LHC) foresees the replacement of magnets around the interaction points of the ATLAS and CMS experiments. One of these is the recombination dipole MBRD (Main Bending Recombination Dipole), or D2. It consists of a cosine-theta magnet, double aperture with same polarity, wound with a Nb-Ti...

The quest for advancing science and technology continues with the Future Circular Collider (FCC), which requires 16 T bending dipoles to be installed along its 100 km tunnel to achieve a center-of-mass energy of 100 TeV, in its hadron-hadron version. The promising Nb_3Sn technology for superconducting magnets presents a potential solution for...

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 θ 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·m, in a 105 mm bore. The project includes...

A thermal calorimetric apparatus was designed, built and calibrated for measuring the activity of the artificial 144 Ce-144 Pr antineutrino source. This measurement will be performed at the Laboratori Nazionali del Gran Sasso in Italy, just before the source insertion in the tunnel under the Borexino detector and a precision better than 1% is...

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...

The Superconducting Ion Gantry (SIG) project aims to design, construct, and test a curved superconducting dipole demonstrator magnet for an ion gantry (up to a rigidity of 6.6 Tm). The main demonstrator magnet parameters are a dipolar field of 4 T generated into a toroidal aperture with an 80 mm diameter, 1.65 m curvature radius, and 30°...

A new generation of superconducting magnets for applications in ion therapy is under study in the frame of a collaboration between CERN, Centro Nazionale di Adroterapia Oncologica (CNAO), Istituto Nazionale di Fisica Nucleare (INFN) and MedAustron. One of the most critical aspects of these new ion therapy facilities is the optimization of...

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...

The Borexino detector has convincingly shown its outstanding performances in the low energy regime through its accomplishments in the observation and study of the solar and geo neutrinos. It is then an ideal tool to perform a state of the art source-based experiment for testing the longstanding hypothesis of a fourth sterile neutrino with ∼ eV...

The Borexino detector has convincingly shown its outstanding performance in the in the sub-MeV regime through its unprecedented accomplishments in the solar and geo-neutrinos detection, which make it the ideal tool to unambiguously test the long-standing issue of the existence of a sterile neutrino, as suggested by several anomalies: the...
