Abstract :
High power THz radiation sources - gyrotrons are being applied to high power THz technologies including enhancement of NMR sensitivity by a dynamic nuclear polarization, direct measurement of hyperfine structure of positronium, X-ray detected magnetic resonance measurement, sub-THz ESR echo spectroscopy and new medical technology. In this paper, such applications of THz gyrotrons are presented.
