Neurospin is a neuroscience research center located in France at CEA Saclay. The facility is already hosting several MRI magnets and Iseult, an innovative Whole Body 11.7 T MRI system, will be available very soon.
The core part of Iseult is an actively shielded NbTi magnet cooled with a superfluid helium bath at 1.8K, that will provide a homogeneous field of 11.7 T within a 90 cm warm bore....
We are developing a helium-free 3T-MRI high-temperature superconducting magnet for whole-body imaging using REBCO wire. The development of a meter-class REBCO magnet has few practical examples, and the problem in the manufacture has not been clarified. Therefore, we grasped the characteristics of REBCO coils by manufacturing meter-class coils and evaluating the current-voltage characteristics...
Curved superconducting bending magnets have clear potential for compact hadron therapy gantries and medical synchrotrons. A combined function superconducting bending magnet design based on collared cos-theta coils is proposed for a novel compact hadron therapy gantry initiative, SIGRUM. These 3 T magnets, based on the technologies extensively developed for the LHC project, include several...
The innovative concept of using a combination of two identical superconducting bend magnets working at a fixed field in a proton therapy gantry, allows for a light and compact design, while being able to deliver protons over a range of 70-230 MeV. In this concept, the gantry is conceived as achromatic, allowing the magnets to operate at a constant field, and therefore avoiding the technical...
A collaboration between CERN, CNAO, INFN and MedAustron has been formed with the aim at designing a light rotating gantry suitable for hadron therapy based on 430 MeV carbon ion beams. After a preliminary design based on 3 T dipole field, now the collaboration is engaging to improve the design to 4 T or more. The magnets are designed according to cosθ layout to be wound with Nb-Ti...
The use of carbon ions in particle therapy can enhance the treatment quality, introducing higher biological effectiveness compared to photons and protons.
Rotating gantries are nowadays used to deliver particle beams from different directions to obtain precise conformal dose mapping at the tumour location. The mechanical stability requirements during the rotation usually require heavy...
We aim to develop a high-resolution 1.3 GHz (30.5 T) nuclear magnetic resonance (NMR) LTS/HTS magnet operated in the persistent-mode. For this magnet, superconducting joints between HTS tapes are indispensable. We have already developed a persistent-mode 400 MHz (9.39 T) LTS/REBa2Cu3Oy (REBCO, RE = Rare Earth) NMR magnet with superconducting joints between...
One of important application for HTS bulk magnets is compact NMR/MRI. We have developed a single-sided (unilateral) HTS bulk magnet and a home-built NMR spectrometer to get NMR relaxometry signals from the sample on the outside of the magnet. The NMR signal relaxation rate, the only parameter that is observed in NMR relaxometry, still gives us the information about the mobility of molecules,...
