Preliminary results of final test of the GHMFL 40 T hybrid magnet

The Grenoble High Magnetic Field Laboratory (GHMFL) has completed the development of a 40-T Hybrid Magnet System to support research in steady, high magnetic fields. Oxford Instruments Superconducting has carried out the design, development and construction of the superconducting outsert system for the hybrid magnet. The superconducting magnet has been successfully tested in steady conditions on its own in a bucket-dewar at 2.8 K and at fields up to 7 T. Subsequently, the magnet has then been assembled in its cryostat in Grenoble in its final position. The magnet has been cooled down to 1.8 K and an additional test is being carried out. The resistive magnet is presently being assembled. A description of the system, its manufacture processes and main test results obtained so far will be presented.
