Corrugated transmission line systems for 395 GHz/600 MHz and 460 GHz/700 MHz DNP-NMR spectroscopy

摘要

We present the design, initial installation and test results of two corrugated waveguide transmission line systems for coupling terahertz power from gyrotrons to two different solid-state Dynamic Nuclear Polarization - Nuclear Magnetic Resonance (DNP-NMR) spectrometers at 600 MHz and 700 MHz (H). The first system combines the power from two different tunable 460 GHz gyrotrons to the DNP-NMR experiment while the second line couples power from a single 395 GHz tunable gyrotron to the DNP-NMR experiment. The lines are currently being installed at the Institute of Protein Research in Osaka University. Test results of individual components and system level test results will be presented.
