Projet FASUM – Fourty Tesla All Superconducting User Magnet
Le projet :
The FASUM (Fourty Tesla All Superconducting User Magnet) project, a forty-tesla all-superconducting magnet providing easy access for future users, is a joint project of the CNRS LNCMI and Grenoble Alpes University.
This 40 T all-superconducting magnet is a combination of a large “commercial” low-temperature superconducting (LTSS) magnet, into which is inserted an insert made from high-temperature superconductors (HTS) with excellent mechanical properties and very high current density at low temperatures and high magnetic fields.
Desired objectives :
The aim is to provide the entire community of users of intense magnetic fields with an innovative experimental device that will enable long, high-quality measurements at magnetic fields that exceed current capabilities (28 T). Such measurements are currently impossible in existing magnets, whether resistive (measurements are expensive, and temporal stability and spatial homogeneity insufficient), pulsed field (long measurements are not possible), or superconducting field (limited to 28 T on a routine basis today).
The aim is to strengthen fundamental and applied research in today’s most active areas: materials for energy, quantum materials and studies of superconductors for nuclear applications (fusion). Medical MRI is also concerned by this project, as the increase in magnetic fields enhances the resolution of MRI, particularly functional MRI.

UpAlim – Installation of a HVB (225 kV) / HTA (15/20 kV) delivery substation – 60MVA
Increase in the power of the LNCMI’s scientific facilities to reach world-class levels of excellence for magnetic field values. This cutting-edge equipment opens up new prospects for international research teams, enabling LNCMI to propose new experiments and reduce electricity consumption by cutting transport losses.
The new transformer financed by ERDF funds from the Auvergne-Rhône-Alpes region and CNRS is now in place on the CNRS campus in Grenoble!
The Laboratoire National des Champs Magnétiques Intenses, one of the CNRS’s major research facilities, is now directly connected to the 225,000 V high-voltage grid managed by RTE at national level.
With a power rating of 60 MVA, this transformer can now increase the power distributed to electromagnets for intense magnetic fields from 24 to 30 MW. Equipped with a new-generation fast-response voltage regulator, this transformer provides better management of the network voltage during the magnetic field ascent and descent phases piloted by the researchers.
The immediate benefit for the international user community is improved stability and a greater margin of safety during experiments in very intense fields. In addition, current magnet tests and developments aim to increase the magnetic field values available in different configurations, taking advantage of the extra power now available.
Finally, direct connection to a high voltage level enables us to reduce joule losses and become a player in the regulation of the national power grid. These are essential building blocks for the long-term sustainability of our scientific activities!
This operation was co-financed by the European Union, the Auvergne-Rhône-Alpes Region and the Centre National de la Recherche Scientifique.
