Application of Continuously Frequency-Tunable Sub-MMW Gyrotron to Dynamic Nuclear Polarization at 14.1 T and 30 K for NMR

摘要

A continuously frequency tunable gyrotron generated submillimeter wave at 395 GHz over a bandwidth of 1 GHz with a power of 10 W. This gyrotron enabled the optimization of high-field dynamic nuclear polarization for the sensitivity enhancement of solid-state NMR without changing the static magnetic field.
