A gyrotron operating at the second cyclotron harmonic in a magnetic field of 9.7 T has produced a CW output power of 25 W at 527 GHz. The gyrotron is now being employed in Dynamic Nuclear Polarization (DNP) Applications. The gyrotron design and results of the tests are presented.
We will present the theoretical design and experimental results from a fundamental cyclotron mode 198 GHz, 5W and a second harmonic 395 GHz, 20 W gyrotrons being developed for application in Dynamic Nuclear Polarization (DNP) enhanced NMR spectroscopy.
The design, operation, and characterization of a continuous-wave (CW) tunable second-harmonic 460-GHz gyrotron are reported. The gyrotron is intended to be used as a submillimeter-wave source for 700-MHz nuclear magnetic resonance experiments with sensitivity enhanced by dynamic nuclear polarization. The gyrotron operates in the whispering-gallery mode TE11, 2 and has generated 16 W of output power...
