“…The reduced operating temperature is achieved using a pump running continuously on the helium reservoir (Warner 2008). As a part of the French- n/a n/a n/a n/a German research project Iseult/INUMAC the design and manufacture of an actively shielded 11.7 T with a 90 cm bore is advancing (Vedrine et al 2008 and references therein; Schild et al 2010). The magnet system will be built by CEA/Dapnia/Irfu.…”

“…The main coil is built up from an arrangement of modules of double pancake windings. This configuration allows direct contact of the superconductor with super fluid helium (T = 1.8 K) and thus the system benefits from cryostabilization (Vedrine et al 2008;Schild et al 2010). …”

“…As shown in Table 6, the magnet will store about 340 MJ when operating at about 1,500 A. Owing to the high operating current, the number of inter-double pancake joints and the high stored energy the magnet will operate in a non-persistent mode using a highly stabilized power supply permanently connected to the magnet (Vedrine et al 2008). The development of 11 T whole body magnets is an attractive field for magnet designers so that a new concept study was published recently (Wada et al 2010).…”

“…The objective of the French-German project Iseult / INUMAC is to develop a whole-body 11.7 T magnetic resonance imaging device (MRI) to improve sensitivity, spatial, temporal and spectral resolution for preclinical and clinical MRI system [1]. This 900 mm bore, very high field whole body magnet, is being developed on the basis of Niobium-Titanium (NbTi) superconductors (cf.…”

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. Abstract. This study deals with an experimental methodology developed in order to identify the elastic properties of superconducting ring-shaped windings, constituents of the main coil winding of a magnetic resonance imaging magnet (MRI). Mechanical tensile tests were conducted on real scale specimens associated to an optical full-field displacement measurement technique (stereo image correlation). Strain fields were then obtained from the measured displacement fields by numerical differentiation. Finally, the four in-plane orthotropic stiffnesses of the windings were determined using the Virtual Fields Method (VFM). Experimental set-up also allows detecting a possible occurrence of a delamination thanks to in-plane displacement fields.

“…In this context, the CEA is intending to build the biggest MRI magnet ever made, an 11.75 T full body imaging system called ISEULT [1]. Given the complexity of the coil, it is expected that the magnet will not be able to work in persistent mode.…”
