Abstract :
First, the successful development and testing of a 2.6 cm inner diameter, high field and high current density solenoid, wound with a Cu-stabilized, fine filamentary Nb3-Sn cable, and reacted after winding, is described. At an overall current density in the winding of 352 frac{A}{mm^{2}} corresponding to a current density of 565frac{A}{mm^{2}} in the non-insulated cable, a maximum field of Bm= 8.8 T had been obtained without any training. Based on this very positive result, a 0.9 m-long, 10 cm-warm bore, beam line quadrupole magnet, wound with the same cable, is actually being assembled. The nominal parameters are : field gradient 74frac{T}{m} , maximum field in the winding Bm= 7.4 T at an overall current density in the winding of 300frac{A}{mm^{2}} . The very specific technological and design aspects of this magnet, related to the "wind and react" technique, such as the conductor insulation, coil winding technique, execution of connections etc, will be discussed. Actually, the four coils for the quadrupole magnet have been manufactured and the assembly of the magnet started. We expect to perform the first tests early next year.
