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 Nb
3-Sn cable, and reacted after winding, is described. At an overall current density in the winding of

corresponding to a current density of

in the non-insulated cable, a maximum field of B
m= 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

, maximum field in the winding B
m= 7.4 T at an overall current density in the winding of

. 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.
