Abstract
A high field NMR magnet system, up to 17 Tesla at 2.0 K with magnet bore of 52 mm was developed. This magnet system will be used to perform NMR experiments in the field of condensed matter physics. The magnet consists Nb/sub 3/Sn and NbTi solenoids. The central field is 15 T at 4.2 K and 17 T at 2.0 K. The field homogeneity is better than 10 ppm over 1 cm diameter sphere volume without shims. The magnet can be operated in the persistent mode and driven mode. A persistent switch was installed on the magnet and the field decay rate was less than 5 ppm/hour in persistent mode operation. The complete magnet was built into a cryostat equipped with a lambda plate refrigerator. In this paper, the magnet test results are presented.
