Modelling of macroscopic magnetic islands in tokamaks

Olivier Sauter, Ivo Furno, Andrei Martynov

The article presents experimental and theoretical investigations on the dynamics of saw-teeth and neoclassical tearing modes in tokamak plasmas. The main findings of these investigations are: (1) The experimental validation, on the basis of FTU and TCV dat ...

Photoabsorption and core-level photoemission study of ruthocuprates

Giorgio Margaritondo, Luca Perfetti

We report on x-ray photoemission and absorption measurements on ruthocuprate and SrRuO3 samples. The ruthocuprates include samples that are both weak ferromagnets and superconductors for part of the phase diagram. The results indicate that adding hydrogen ...

Development of a Novel Printed Circuit Board Technology for Inductive Device Applications

Martinus Gijs

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 ...

A problem of magnetostatics related to thin plates

Jean Descloux

Motivated by an industrial project concerning the electrolysis cells for the production of aluminium, we study the asymptotic behaviour of ferromagnetic plates first when the magnetic susceptibility is large and then when the thickness of the plates is sma ...

Superconductors for fusion magnets: realizations, prototypes and running projects

Pierluigi Bruzzone

This paper gives a review of the application of superconductivity to nuclear fusion magnets. For each machine, a short description emphasizes the special features of the winding technology and conductor design. A selection of demonstration magnets is prese ...

Ring Currents in Icosahedral C60

Alfredo Pasquarello

A new formulation of the current within the London approximation allows the calculation of ring currents in topologically complex molecules. Application of this theory to C60 demonstrates the existence of remarkable pi-electron ring currents. Paramagnetic ...

Diamagnetic currents

Nicolas Macris

Abstract We study the diamagnetic surface currents of particles in thermal equilibrium submitted to a constant magnetic field. The current density of independent electrons with Boltzmann (respectively Fermi) statistics has a gaussian (respectively exponent ...
