Rotating coils, flux metric method, wire systems
/ Fiscarelli, Lucio (speaker) (CERN)
The measurement of the magnetic field is often the final verification of the design and fabrication process of a magnets for particle accelerators.
In most cases, when seeking high accuracy, the measurement technique and its realization can result in a considerable effort. The lecture describes
the most used field-measurement techniques based of flux-metric methods:
i)the rotating coil method gives a complete two-dimensional description of the magnetic field in terms of normal and skew multipoles;
ii) static coils are employed in case of fast-ramped or curved magnets;
iii) the single stretched wire is the reference instrument to measure field
integrals and to find the magnetic axis..

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.
