State of the art and developments of high field magnets at the 'Laboratoire National des Champs Magnetiques Intenses'

Most accelerators would benefit from higher average electric charges and higher intensities of the ion beams which implies the necessity to produce higher magnetic fields with complex topologies and high gradients. The 'National Laboratory of Intense Magnetic Fields' (LNCMI) is the result of the merging of the 'Laboratory of Intense Magnetic Fields' in Grenoble specialized in the generation of DC magnetic fields and the 'National Laboratory of Pulsed Fields' in Toulouse specialized in the generation of pulsed magnet fields. DC fields of up to 35 T, pulsed fields up to 80 T and single-shot pulsed fields up to 170 T are provided to an international community of users. In the present paper we present the current state of our installations and the developments which are pursued in the context of an increasing international competition. The challenge for the future is to combine the use of high DC magnetic fields with other large facilities like synchrotrons or neutron sources. For this purpose, developments of innovative hybrid systems including high temperature superconducting materials are essential. (authors)
