Manufacturing, installation, commissioning, and first results with the 3D low-temperature co-fired ceramic high-frequency magnetic sensors on the Tokamak a Configuration Variable

Duccio Testa

Innovative high-frequency magnetic sensors have been designed and manufactured in-house for installation on the Tokamak a Configuration Variable (TCV), which are now routinely operational during the TCV experimental campaigns. These sensors combine the Low ...

Wideband Multiport Antennas

Anja Skrivervik, Abdulkadir Uzun

In this paper, a wideband four port 2-6 GHz antenna is proposed. One-, two-, and four-port antennas are implemented and characterized between 2 and 6 GHz. The isolation between the ports is improved by connecting and optimizing the ground plane sections. T ...

RF sheath modeling of experimentally observed plasma surface interactions with the JET ITER-Like Antenna

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Jonathan Graves, Yves Martin, Duccio Testa, Patrick Blanchard, Alessandro Pau, Henri Weisen

Waves in the Ion Cyclotron Range of Frequencies (ICRF) enhance local Plasma-Surface Interactions (PSI) near the wave launchers and magnetically-connected objects via Radio-Frequency (RF) sheath rectification. ITER will use 20MW of ICRF power over long puls ...

EM Fields Generated by a Scale Model Helical Antenna and Its Use in Validating a Code for Lightning-Induced Voltage Calculation

Farhad Rachidi-Haeri

This paper aims at validating a code for the evaluation of lightning-induced overvoltages developed in the PSCADEMTDC environment using experimental results obtained on an experimental facility deployed at the University of S˜ao Paulo, Brazil that emulates ...

Importance of Taking Into Account the Soil Stratification in Reproducing the Late-Time Features of Distant Fields Radiated by Lightning

Marcos Rubinstein, Antonio Sunjerga, Farhad Rachidi-Haeri, Qi Li, Mi Zhou

In this paper, we present an analysis of the propagation effect along a lossy ground on the characteristics of lightning-generated electric fields, using simultaneous observations of lightning currents and radiated fields measured at nine different distanc ...

The JET upgraded toroidal Alfven Eigenmode Diagnostic System

Ambrogio Fasoli, Duccio Testa, Patrick Blanchard

The Alfven Eigenmode Active Diagnostic system (AEAD) has undergone a major upgrade and redesign to provide a state-of-the-art excitation and real-time detection system for JET. The new system consists of individual 4 kW amplifiers allowing for increased cu ...

Impact of ICRF on the scrape-off layer and on plasma wall interactions: From present experiments to fusion reactor

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Yves Martin, Duccio Testa, Jonathan Graves, Henri Weisen, Dalziel Joseph Wilson, Yu Lin

Recent achievements in studies of the effects of ICRF (Ion Cyclotron Range of Frequencies) power on the SOL (Scrape-Off Layer) and PWI (Plasma Wall Interactions) in ASDEX Upgrade (AUG), Alcator C-Mod, and JET-ILW are reviewed. Capabilities to diagnose and ...

Broadbeam microstrip patch antenna using higher order modes

Anja Skrivervik, Ismael Vico Triviño

The aim of this contribution is to assess the potential of using various microstrip radiating elements excited with different modes to achieve wide pattern beamwidths. The proposed antenna is made in classic microstrip technology and consists of a circular ...

Aperture-Coupled Low-Profile Wideband Patch Antennas for CubeSat

Anja Skrivervik, Miroslav Veljovic

This communication presents the design and measurement results of aperture-coupled stripline-fed wideband patch antennas for nanosatellite applications. The low-profile requirements lead to a strong back radiation from the coupling aperture. Instead of sup ...

Electrically small antenna design: from mobile phones to implanted sensors

Anja Skrivervik, Zvonimir Sipus

In this review, intended to introduce the convened session on electrically small antennas, we describe the evolution of electrically small antennas from the early nineties, when the boom of mobile phones triggered an intense research activity on the, to ou ...
