Outline of Final Research Achievements |
By irradiation of high power sub-THz radiation on the sample, we can transfer the polarization of electron spins to nuclear spins and as the result, enhance the sensitivity of NMR spectroscopy by higher than 1000 times for application to analysis of complicated protein molecule. For such objectives, we have developed two 460GHz gyrotrons with following functions; frequency tunability, high power of 100W and long term continuous stable operation during longer than ten hours. We have installed these two gyrotrons on 700 MHz NMR spectrometer at Osaka University, Institute of Protein Research for DNP-NMR experiment and succeeded in the highest frequency DNP-NMR spectroscopy.
