Abstract

Sub-THz gyrotrons with the functions of frequency control are useful for application to high power sub-THz spectroscopy including a DNP enhanced high-sensitive NMR spectroscopy. Continuous frequency tunability, frequency modulation and frequency step-changing will be achieved for our Gyrotron FU CW Series and such special functions of frequency control are applied for additional enhancement of NMR sensitivity. In this paper, it will be presented how such functions are achieved and how about the advantages of them for sensitivity enhancement of NMR spectroscopy.
