Comparison of detailed experimental wavenumber spectra with gyrokinetic simulation aided by two-dimensional full-wave simulations
T. Happel,Tobias Görler,Pascale Hennequin,C. Lechte,M. Bernert,G. D. Conway,Simon Freethy,Cyrille Honoré,J. R. Pinzon,Ulrich Stroth +9 more
TL;DR: Happel et al. as mentioned in this paper presented experimental wavenumber spectra which show pronounced differences, although they are measured at the same toroidal, poloidal and radial location, and the differences are due to the probing beam polarization.
140 GHz, 1 MW CW Gyrotron Development for Fusion Applications—Progress and Recent Results
Gerd Gantenbein,V. Erckmann,Stefan Illy,Stefan Kern,W. Kasparek,C. Lechte,W. Leonhardt,Christophe Lievin,Andrey Samartsev,Andreas Schlaich,Martin Schmid,Manfred Thumm +11 more
TL;DR: A 10MW, 140 GHz ECH system is currently under construction for the stellarator W7-X as mentioned in this paper, where the RF power will be provided by 10 gyrotrons.

Numerical Calculation of Reflection Characteristics of Grooved Surfaces with a 2D FDTD Algorithm
TL;DR: In this paper, a method was developed to calculate the reflection of microwaves at corrugated metallic surfaces along with the expected ohmic losses and phase shifts and an optimized corrugation profile was suggested.

Numerical and experimental investigation of a 5-port mitre-bend directional coupler for mode analysis in corrugated waveguides
TL;DR: In this paper, a directional coupler array with 5 ports integrated into a mitre bend for corrugated waveguide transmission lines at 140 GHz has been manufactured, and calculations on the performance for in-situ power measurement and mode discrimination are shown.
