| Outline of Final Research Achievements |
By irradiation of high power sub-THz radiation from gyrotrons, magnetic polarization of electron spin is transfered to nuclear spin which results in the high sensitive NMR spectroscopy by use of dynamic nuclear polarization (DNP) effect. In this work, we will achieve further enhancement of NMR sensitivity by add following three functions on the gyrotrons,
1) By the modulation of an electron beam energy, we will achieve the frequency modulation of gyrotron output in order to extend the ESR resonance width and increase the number of electron spin which contribute to DNP. 2) By stabilization of the electron beam current, we will achieve the long-term stable gyrotron operation. 3) By making the gyrotron system compact, we can access the gyrotron system to big scale NMR spectrometer system.
