Development of Novel Spectroscopic Magnet Combining Mass Spectroscopy With Nuclear Magnetic Resonance

We developed a superconducting magnet which is suitable for a novel spectroscopy. The methodology of the spectroscopy was suggested by Fuke. This enables to combine NMR (Nuclear Magnetic Resonance) spectroscopy with mass spectroscopy. In order to realize the spectroscopy, the magnet needs two homogeneous regions of 12 T and 4 T, respectively. The field gradient between two regions is required to be high enough. The coil structure is robust against high stress due to such an asymmetric field. The magnet is shielded actively and has a horizontal access room temperature bore of 155 mm diameter.
