【 摘 要 】

LNCMI is one of the unique worldwide laboratories offering the scientific community access to various experimental conditions with continuous magnetic fields well above 20 T. LNCMI is currently developing a large field flexible experimental platform. One configuration will produce a continuous magnetic field of 43 T in a 34 mm warm bore aperture from the combination of homemade resistive electromagnet inserts and a large bore outer superconducting magnet (1.1 m internal cold dia.), the latter being built in close collaboration with CEA-IRFU Saclay. The superconducting magnet with its mechanical structure and its helium vessel will represent a mass of 22 tons to cool down to 1.8 K and maintain at this temperature 10 months per year. An overview of the project will be given focusing on the cryogenics and particularly on the helium liquefier designed and manufactured by Air Liquide Advanced Technologies. This system - the most powerful even produced in the Helial ML range - and its ancillaries has been integrated and commissioned as a turnkey system in the existing site of LNCMI.
