摘要：

One possible application of Nb3Sn, whose superconducting properties far exceed those of NbTi, is the fabrication of short and powerful quadrupole magnets for the crowded interaction regions of large particle accelerators. To learn about Nb3Sn technology and to evaluate fabrication techniques, DAPNIA/STCM at CEA/Saclay has undertaken an R&D program aimed at designing and building a 1-m-long, 56-mm-single-aperture quadrupole magnet model. The model relies on the same coil geometry as the LHC: are quadrupole magnets, but has no iron yoke. It is expected to produce a nominal field gradient of 211 T/m at 11,870 A. The coils are wound frail; Ruthorford-type cables insulated with quartz fiber tapes, before being heat-treated and vacuum-impregnated with epoxy resin. Laminated, austenitic callers, locked around the coil assembly by means of kegs restrain the Lorentz forces. After reviewing the conceptual design of the magnet model, we report on the cable and cable insulation development programs and we present the results of NbTi-Nb3Sn cable splice tests.
