Bilfinger Noell successfully delivers superconducting magnet to CNRS LNCMI-Grenoble


Bilfinger Noell manufactured the large aperture superconducting outsert coil for the Grenoble hybrid magnet combining resistive and superconducting technologies. This superconducting coil weighing approximately 20 tons is made by the stacking of 37 interconnected double pancake coils. It was delivered in February 2020 to the Laboratoire National des Champs Magnétiques Intenses (LNCMI), a CNRS research facility located in Grenoble.

The outsert superconducting coil will be cooled by a bath of pressurized superfluid helium to operate at 7,115 A and 1.8 K providing a magnetic field of 8.5 Tesla. In combination with resistive insert magnets developed at LNCMI-Grenoble and connected to the 24 MW electrical powered installation of the laboratory the hybrid magnet will provide a total continuous magnetic field of up to 43 Tesla.

The Grenoble hybrid magnet would open new dimensions for research in most disciplines such as for example in condensed and dilute matter physics, material science, magneto-science, chemistry, cosmology and particle physics with a new experiment for cold dark matter search.
