One possible application of Nb 3 Sn is the fabrication of short and powerful quadrupole magnets for the crowded interaction regions of large particle accelerators. To learn about Nb 3 Sn technology and evaluate fabrication processes, CEA/Saclay has undertaken a R&D program aimed at designing and building a quadrupole magnet model. After a brief review of the mechanical design, we report on mechanical computations carried out to optimize the magnet straight section. The DAPNIA/STCM at CEA/Saclay has undertaken an R&D program to design and build a single-aperture quadrupole magnet model with a Nb 3 Sn Rutherford-type cable. Nb 3 Sn can be used either to achieve a high magnetic field gradient in a large aperture or to permit magnet operation in a sizeable background magnetic flux density. The conceptual design of a 1-m-long, 56mm-single-aperture Nb 3 Sn quadrupole magnet, with a nominal field gradient of 211 T/m at 11870 A and 4.2 K is presented. Then, we report the main results of FE computations performed to optimize the magnet coil prestress. This R&D program is aimed at the final focus system of the TESLA linear collider now under consideration at DESY. 1
