Abstract :
A high homogeneity magnet, up to 14 Tesla at 4.2 K with magnet bore of 74 mm was developed. This magnet is the starting point in order to develop a 600 MHz/52 mm magnet system for NMR spectroscopy. The field homogeneity is better than 5 ppm over 1 cm diameter sphere volume without any shim-coils. The magnet can be operated in persistent mode and driven mode. The required magnetic field decay rate is 0.1 ppm/hour. A quench analysis has been studied. Magnetic and structural analysis has been performed. Main data of the magnet system, phases of technological development and test results are reported in this paper.
