Performance Comparison of Cables With Partial Transposition

Pierluigi Bruzzone, Kamil Sedlák, Federica Demattè, Chiara Frittitta

The need of full transposition of the current carrying elements (strands) in large cables is frequently retained as top design criterion for conductors operating in pulsed mode. However, when the transposition error, i.e., the inductance difference among t ...

Metal-wire-embedded alumina insulating material using micro- and nanoscale 3D printing for surface flashover mitigation in a vacuum

Guang-Yu Sun

A micro- and nanoscale 3D printing technique is applied to fabricate a functional insulating material that mitigates surface discharge in a vacuum based on microscopic electron multipactor suppression. The proposed alumina ceramic insulator design consists ...

Strain-induced polar discontinuities in two-dimensional materials from combined first-principles and Schrodinger-Poisson simulations

Giovanni Pizzi, Marco Gibertini, Augustin Bussy

The local application of mechanical stress in piezoelectric materials gives rise to boundaries across which the electric polarization changes. Polarization charges appear along such polar discontinuities and the ensuing electric fields drive a charge recon ...

Nuclear Quantum Effects in H+ and OH- Diffusion along Confined Water Wires

Michele Ceriotti, Mariana Rossi Carvalho

The diffusion of protons and hydroxide ions along water wires provides an efficient mechanism for charge transport that is exploited by biological membrane channels and shows promise for technological applications such as fuel cells. However, what is lacki ...

Large-scale fabrication of titanium-rich perovskite PZT submicro/nano wires and their electromechanical properties

Nava Setter, Jian Wang, Silviu Cosmin Sandu

We report a 2-step approach to prepare tetragonal perovskite PbZr0.1Ti0.9O3 submicro/nano wires in gram scale and with over 95% wire content. Non-perovskite precursor wires were first fabricated by hydrothermal processing. A subsequent annealing in a PbO a ...

A single nanotrench in a palladium microwire for hydrogen detection

Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Oscar Vazquez Mena, Thomas Kiefer

The hydrogen sensing characteristics of a single nanotrench fabricated by focused ion beam milling (FIB) in an evaporated palladium microwire are presented. In situ atomic force microscopy (AFM) measurements proved that, in the presence of H2, the trench c ...

Test results of a large size, forced flow Nb3Sn conductor, based on a design alternative to the cable-in-conduit

Pierluigi Bruzzone, Boris Stepanov, Rainer Wesche, Martin Vogel

An R&D program at CRPP investigates the design of large size Nb3Sn conductors, with the aim to improve the effectiveness and hence the cost of large size, force flow conductors. A design based on a solder filled flat cable, by react wind method, is selecte ...

Kink instability of flux ropes anchored at one end and free at the other

Ivo Furno

The kink instability of a magnetized plasma column (flux rope) is a fundamental process observed in laboratory and in natural plasmas. Previous theoretical, experimental, and observational work has focused either on the case of periodic (infinite) ropes (r ...

Influence of Ta and Ti Doping on the High Field Performance of (Nb,Ta,Ti)(3)Sn Multifilamentary Wires based on Osprey Bronze with High Tin Content

Davide Uglietti

Ta and Ti are the most widely used additions for technical Nb3Sn multifilamentary superconductors. These elements are known to influence grain growth, grain morphology and chemical composition in the A15 layer, hence the current carrying properties of the ...
