The new magnet system to be installed at the European Synchrotron Radiation facility (ESRF) in Grenoble is designed to reach 9 T in the direction parallel to the beam and 4 T in the perpendicular direction. The two fields are not generated simultaneously. A high sweeping rate, 0-B(max) within 1 min, is specified. An innovative solution with respect to the traditional magnets available on the market is proposed.
Two different conceptual options are considered. The first consists in using a split solenoid in NbTi for the main field and a pair of NbTi racetrack coils nested inside the solenoid for the perpendicular field. The second option foresees a split solenoid with both NbTi and Nb(3)Sn grades for the main field and a pair of NbTi saddle shape coils outside the solenoid for the perpendicular field. The study has focused only on this last solution, since the first option does not allow the field requirements to be satisfied.
Finite element electro-magnetic models are developed and run iteratively in order to define the main characteristics (size, current density, field and temperature margins) of the magnet. The activity also includes the conductor design and specification, ac loss and heat removal rate assessment, design of the supporting structure for the windings and cooling layout sketches.
