In this paper, the authors further validate a theory presented previously by themselves for evaluating currents induced by external electromagnetic fields on a finite-length horizontal wire above a perfectly conducting ground. They present an approach to g ...
A simple configuration that consists of a set of toroidal, helical and vertical field coils is used to calculate free boundary equilibria with non-zero plasma current and approximately helically symmetric plasma boundary shape. The amount of helical bounda ...
We have adapted a new printed circuit board (PCB) technology to the fabrication of ultraflat and sensitive fluxgate magnetic field sensors. The two outer layers of the PCB stack compose the electrical windings of fluxgates, while the inner layer is made of ...
This paper describes the fabrication and characterisation of 2-dimensional inductive devices integrated inside printed circuit boards . PCB and flex-foils. These devices basically are composed of three layers of which the outer layers bear the printed coil ...
We have developed a cheap and simple trilayer printed circuit board (PCB)-based technology, adapted for the fabrication of fluxgate magnetic sensors. The two outer layers of the PCB stack comprise the electrical windings of the fluxgate, while the inner la ...
Results from the first experiments to drive Alfven Eigenmodes (AEs) with antennas external to a tokamak plasma are presented. In ohmically heated plasma discharges, direct experimental measurements of the damping of toroidicity induced AEs (TAEs) have allo ...
Density limit disruptions have been studied during the current flat-top of TCA. Disruption occurs at two different densities, depending on discharge programming. The highest densities are achieved by a strong influx of neutral gas called 'hard gas puffing' ...
Numerical calculations are presented to show the influence of pressure and inductance on the vertical stability of shaped tokamaks. High values of epsilon beta(p) improve the vertical stability of dee shaped tokamaks but are destabilizing for an inverse de ...
We report measurements made on hybrid arrays consisting of superconducting wires along one direction of a square geometry and Josephson junctions along the perpendicular direction. The differential resistance Rd across the array as a function of normalized ...
A system of integral-differential equations for evaluating currents and voltages induced by external electromagnetic fields on a finite-length horizontal wire above a perfectly conducting ground is derived under the thin wire approximation. Based on pertur ...
