Liu, Diwei, Tao Song, Hao Shen, Jie Huang, Ning Zhang, Chenghai Wang, Wei Wang, and Shenggang Liu. “High Power Continuously Frequency-Tunable Terahertz Radiation Sources and Transmission Lines for DNP-Enhanced NMR System.” In 2018 43rd International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 1–2. Nagoya: IEEE, 2018.
The effect of the electron beam quality of a 250GHz continuously frequency-tunable gyrotron used for Dynamic Nuclear Polarization enhanced Nuclear Magnetic Resonance is tuned by changing the operating voltage V0 or the operating magnetic field B0 on the operating frequency and the beam-wave interaction efficiency is investigated. Meanwhile, an improved transmission and mirror system with a well-focused Gaussian-like output beam is designed to match the DNP-NMR sample.

A quasi-optical and corrugated waveguide microwave transmission system for simultaneous dynamic nuclear polarization NMR on two separate 14.1 T spectrometers #DNPNMR
Gyrotrons typically generate much more microwave power than needed in a DNP-NMR experiment. This article describes a very nice way how to share the microwave power generated by a single gyrotron between two NMR experiments.
