Colin D. Joye,Robert G. Griffin,M.K. Hornstein,Kan-Nian Hu,K.E. Kreischer,Melanie Rosay,Michael Shapiro,Jagadishwar R. Sirigiri,Richard J. Temkin,Paul P. Woskov +9 more
TL;DR: The operating characteristics of a 140-GHz 14-W long pulse gyrotron used in dynamic nuclear polarization enhanced nuclear magnetic resonance (DNP/NMR) spectroscopy experiments are presented and mode patterns matched reasonably well to theory for both the TE(0,1) mode and theTE(1, 1) mode.
Journal ArticleDOI
UV-LIGA microfabrication of 220 GHz sheet beam amplifier gratings with SU-8 photoresists
TL;DR: In this article, the authors describe methods that have led to successfully fabricated millimeter wave circuits, including applying ultra-thick SU-8 photoresist layers on copper, copper electroforming solutions, and the challenging removal of the photoresists.
Journal ArticleDOI
Demonstration of a 140-GHz 1-kW Confocal Gyro-Traveling-Wave Amplifier
TL;DR: The demonstrated performance of this amplifier shows that it can be applied to dynamic nuclear polarization and electron paramagnetic resonance spectroscopy.
