Electromagnetic Analysis and Validation of an Ironless Inductive Position Sensor

Yves Perriard, Alessandro Danisi, Alessandro Masi

The ironless inductive position sensor is a linear position sensing structure, which exhibits intrinsic immunity to external magnetic fields since it is characterized by air-cored windings. This new solution may be of major interest for applications where ...

Asymmetric Ring/Disk Nanocavities on Conducting Substrates for Strong Fano-Interference

Hatice Altug, Arif Engin Cetin

We introduce a Fano resonant asymmetric ring/disk cavity system employing a conducting layer underneath. Our system shows stronger electromagnetic fields that are highly accessible to surrounding medium and sharper spectral features that result in more rel ...

Magnetic Model of the CERN Proton Synchrotron

Mariusz Juchno

In this thesis, we present development of the first magnetic model of the main Proton Synchrotron magnets. The operation of the machine and conducting research on increasing its performance require a significant amount of the magnetic field data for the op ...

Local Excitation of Magnetostatic Modes in YIG

Jean-Philippe Ansermet, Elisa Papa

Described are ferromagnetic resonance (FMR) studies of the long wavelength magnetostatic wave modes of a single crystal yttrium iron garnet (YIG) slab magnetized by an in-plane field. A resonant circuit comprising a coil, 50 m in diameter, is used to excit ...

High current superconductors for DEMO

Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov

In the assumption that DEMO will be an inductively driven tokamak, the number of load cycles will be in the range of several hundred thousands. The requirements for a new generation of Nb3Sn based high current conductors for DEMO are drafted starting from ...

Thermo-electric analysis of the interconnection of the LHC main superconducting bus bars

Luca Bottura, Pier Paolo Granieri

Spurred by the question of the maximum allowable energy for the operation of the Large Hadron Collider (LHC), we have progressed in the understanding of the thermo-electric behavior of the 13 kA superconducting bus bars interconnecting its main magnets. A ...

Analytical Model for Slotless Permanent Magnet Axial Flux Motors

Yves Perriard

Permanent magnet axial flux motors are very well adapted to applications requiring a very short active length and a big diameter. They also have been used for micro-motors. Because of their size, these motors require the use of a permanent magnet and their ...

Huge critical current density and tailored superconducting anisotropy in SmFeAsO0.8F0.15 by low-density columnar-defect incorporation

Janusz Andrzej Karpinski, Sergiy Katrych, Yihan Jia

Iron-based superconductors could be useful for electricity distribution and superconducting magnet applications because of their relatively high critical current densities and upper critical fields. SmFeAsO0.8F0.15 is of particular interest as it has the h ...

Effect of the TEM Mode on the Kicker Impedance

Carlo Zannini, Giovanni Rumolo

The kickers are major contributors to the CERN SPS beam coupling impedance. As such, they may represent a limitation to increasing the SPS bunch current in the frame of a luminosity upgrade of the LHC. The C-Magnet supports a transverse electromagnetic (TE ...

Modelling and mathematical results arising from ferromagnetic problems

Jacques Rappaz, Jean Descloux

In this article, we investigate the equations of magnetostatics for a configuration where a ferromagnetic material occupies a bounded domain and is surrounded by vacuum. Furthermore, the ferromagnetic law takes the form ...
