並列タイトル等Development for X-band DNP at cryogenic temperature
一般注記As is reported last year, when we tried to perform DNP measurements with a high power light source gyrotron CW-I (f ~ 299.23 GHz), we faced a problem that the sample evaporated during irradiating high power sub-THz wave. Cooling by cryogen is a direct solution of it. We have developed X-band Dynamic Nuclear Polarization (DNP) system at cryogenic temperature. By putting a Dewar vessel into the resonant cavity, we succeeded to observe DNP measurements at liquid nitrogen temperature. Since the BDPA-doped organic solution was frozen, dependence of the DNP enhancement on the applied magnetic field showed the solid effect instead of Overhauser effect.
