TL;DR: In this article, a multi-modal antenna, with sensitivity approximately constant for any incoming linear polarization, with great radiating surface and low directivity has been developed, for collecting 140 GHz stray radiation from FTU tokamak and Wendelstein 7-AS stellarator plasmas during ECRH and current drive experiments.
Journal ArticleDOI

Alessandro Bruschi,S. Cirant,F. Gandini,Gustavo Granucci,V. Mellera,V. Muzzini,A. Nardone,Alessandro Simonetto,Carlo Sozzi,N. Spinicchia +9 more
TL;DR: In this paper, a matched load for high-power measurements and testing of gyrotrons and transmission lines in ECRH plants for fusion research applications is designed, which consists of hollow spheres of copper with the inner wall covered by plasma-sprayed lossy ceramics.

TL;DR: In this paper, high-frequency wave systems with high-power density launching capability have been the preferred choice to heat the Frascati Tokamak Upgrade (FTU) because of physics arguments (electron heating at...
Journal ArticleDOI
Calorimetric loads for high power transmission lines at millimeter wavelengths
Alessandro Bruschi,F. Gandini,V. Muzzini,N. Spinicchia,S. Cirant,G. Gittini,Gustavo Granucci,V. Mellera,A. Nardone,Alessandro Simonetto,Carlo Sozzi +10 more
TL;DR: In this article, two different calorimetric loads were designed to measure the mm-wave power at 140 GHz propagating either as a gaussian beam or as an HE11 mode carried by an oversized corrugated waveguide.
