Abstract
A 9.38 T NMR/MRI spectrometer magnet with a 183 mm warm bore has been designed, built and tested. The field uniformity requirements are 0.6 ppm over 25 mm diameter, 2.0 ppm for 40 mm diameter and 12 ppm for 80 mm diameter. In order to assure the achievement of the field uniformit y, a set of 18 superconducting shim coils was built. In addition, anot her set of 18 resistive shim coils was built to correct the diamagneti sm of the specimen. Result of performance tests for these systems will be described.
