摘要：

A compact 17 T magnet was successfully fabricated and energized using a flexibly supported epoxy-impregnated coil without a bore tube. This coil structure was developed with a magnet stabilization study on small Nb - Ti and Nb3Sn coils. The 17 T magnet is composed of two sets of Nb3Sn coils and an Nb - Ti coil graded into two sections. The magnet successfully attained the designed field, 17 T, in the 33 mm bore. The stabilization contributed to the performance of each coil. No quench occurred in the inner Nb3Sn coil. The stabilization enabled a current density as high as 260 A mm-2, generating 8.8 T, to be achieved for the Nb - Ti coil in a compact system operated in a 300 mm diameter cryostat.
