Outline of Final Research Achievements |
NMR system at higher magnetic fields was developed to improve the NMR resolution and sensitivity. Electric power consumption of a hybrid magnet becomes a serious problem after the Great East Japan Earthquake. Thus, development was applied for an NMR system with a superconducting magnet. The magnet comprises a high Tc superconducting innermost coil and low Tc superconductor outer coils. The magnet was operated in a driven-mode by an external DC power supply. The temporal field stability less than 170 ppb/10h was realized by using an external NMR lock. The homogeneity of the magnetic field was adjusted by superconducting, ferromagnetic and room temperature shims, based on the magnetic field data collected along a spiral locus. A 1H spectrum of CHCl3 with the full-width at half maximum of 0.7 ppb was successfully achieved after these field corrections. Efficiency of high magnetic fields in solid-state NMR was demonstrated by 17O MAS-NMR measurements of B2O3.
