Abstract : A high field wiggler to be inserted in the European Synchrotron Radiation Facility (ESRF), is presented. A peak field in excess of 3.0 Tesla is obtained by means of two superconducting racetrack windings made up with Nb-Ti copper stabilized wires. Current grading is foreseen. With the use of high current densities and a small magnetic gap, half period length of about 8 cm is obtained. In order to null the field integral along the beam through the magnet, two small conventional magnets, to be installed outside the LHe cryostat, are foreseen. The magnetic field for the chosen configuration is calculated by 2 D and 3 D codes. A code has been developed to evaluate the behaviour of the magnet in case of a quench. The X-ray source characteristics have been analysed.
