First developments towards producing inductive magnetic sensors using state-of-the-art photolithography techniques

Duccio Testa, Ambrine Douhane, Marcus Cemes

Inductive magnetic sensors are needed for tokamak operation to provide the low-frequency (LF) measurements leading to the equilibrium reconstruction and to monitor the higher frequency (HF) instabilities; the HF magnetic sensors are often also used as a ba ...

ICRH assisted breakdown study on JET

Benoît Labit, Haomin Sun, Thomas Binderup Jensen

Ion cyclotron (IC) wave assisted breakdown has the potential to increase the robustness of plasma initiation during the ITER pre-fusion operation phase. Studies were performed at JET at ITER relevant loop electric field, E-loop ? 0.33 Vm(-1), and a range o ...

Enhanced-DAB Converter: Comprehensive Design Evaluation

Elison de Nazareth Matioli, Armin Jafari, Furkan Karakaya

Soft switching in dual-active-bridge (DAB) converters enables their efficient operation at high frequencies, where the reduction in the size of magnetic components could result in ultra-high power densities. Nonetheless, losing soft-switching at high frequ ...

Preliminary Tests of Soldered and Diffusion-Bonded Splices Between Nb3Sn Rutherford Cables for Graded High-Field Accelerator Magnets

Pierluigi Bruzzone, Davide Uglietti, Mithlesh Kumar, Vincenzo D'Auria

High-field accelerator magnets of the next generation will require coil grading in order to decrease the amount of superconductor and hence the magnet cost. The joints between Nb3Sn conductor grades must have low electrical resistance (

Modelling of non-linear edge harmonic oscillations and the effect of non-axisymmetric magnetic coils

Jonathan Graves, Wilfred Anthony Cooper, Daniele Brunetti, Andreas Kleiner, Guillermo Bustos Ramirez

Quiescent H-mode (QH-mode) operation is highly desirable relative to the well known H- mode operation because it allows for high energy density in the core as well as potentially im- proved confinement of energy and particles. A feature of QH-mode is that ...

A Reconfigurable Inductor Based on Vanadium Dioxide Insulator-to-Metal Transition

Mihai Adrian Ionescu, Montserrat Fernandez-Bolanos Badia, Emanuele Andrea Casu, Matteo Cavalieri, Andrei Müller, Alessandro Fumarola

This letter introduces a reconfigurable planar square-coil-shaped inductor exploiting as the tuning mechanism the insulator-to-metal transition (IMT) of a vanadium dioxide (VO2) switch placed in the interwinding space in an unprecedented manner. The VO2 th ...

Stabilization of the vertical instability by non-axisymmetric coils

Wilfred Anthony Cooper

In a published Physical Review Letter (Reiman 2007 Phys. Rev. Lett. 99 135007), it was shown that axisymmetric (or vertical) stability can be improved by placing a set of parallelogram coils above and below the plasma oriented at an angle to the constant t ...

Leakage Flux Modelling of Multi-Winding Transformer using Permeance Magnetic Circuit

Drazen Dujic, Min Luo, Jost Allmeling

The size and position difference of the windings determine the leakage flux path and give rise to unbalance of the short-circuit impedances, which strongly affects the transient behaviour of the transformer. This work proposes a new approach of modelling w ...

Electro-thermal virtual prototyping of a Rogowski Coil sensor system

Alain Vachoux, Juan Sebastian Rodriguez Estupinan

An electro-thermal model of a Rogowski Coil sensor system is here described. A co-design methodology between VHDL-AMS and Finite Element Analysis (FEA) has been used for modeling the entire system. The proposed modeling strategy uses geometrical FEA to com ...

Electro-thermal modeling of a Rogowski coil sensor system

Alain Vachoux, Juan Sebastian Rodriguez Estupinan

This paper focuses on the electro-thermal modeling of an electrical current sensor, based on the Rogowski Coil transducer. We exploit the multi-domain capabilities of VHDL-AMS together with geometrical Finite Element Analysis (FEA) to create a time-depende ...
