The main purpose of our research is to develop the tera-hertz wave technique of DNP(Dynamical Nuclear Polarization)-NMR for the protein structural analysis. For such purpose, we have developed two DNP systems (only at room temperature); one is an X-band system with a YIG oscillator and a TWTA, and the other is a tera-hertz wave system with a gyrotron. At first, we have demonstrated the 1H-DNP experiments on BDPA-doped toluene solution at 11.4 GHz ESR frequency. Increase of the signal intensity of 1H-NMR (about 20 times at maximum) has been observed when the microwave was irradiated to the sample effectively by the sample-shuttle system. The tera-hertz wave experiments have been also performed with a gyrotron CW-1, however, we could not avoid increase of the sample temperature, and the DNP effect was not confirmed. We are now looking for the solution to avoid the increase of sample temperature while the high power microwave is irradiated.
