Test results of the ITER PF insert conductor short sample in SULTAN

Pierluigi Bruzzone, Boris Stepanov, Rainer Wesche

A short sample of the NbTi cable-in-conduit conductor (CICC) manufactured for the ITER PF insert coil has been tested in the SULTAN facility at CRPP. The short sample consists of two paired conductor sections, identical except for the sub-cable and outer w ...

Irradiation-induced stacking fault tetrahedra in fcc metals

Nadine Baluc, Zhongwen Yao

Irradiation induces the formation of stacking fault tetrahedra (SFTs) in a number of fcc metals, such as stainless steel and pure copper. In order to understand the role of the material's parameters on this formation, pure Cu, Ni, Pd and Al, having a respe ...

The index n of the voltage-current curve, in the characterization and specification of technical superconductors

Pierluigi Bruzzone

The attention of the fusion magnet specialists has been drawn in the last years to the volt-ampere characteristic (VAC) of the large cable-in-conduit conductors (CICC), as early voltage was observed in conductor and model coil tests, far away from the expe ...

Green oxidation catalysts: computational design of high-efficiency models of galactose oxidase

Leonardo Guidoni

Ab initio calcns. were used for the rational design of efficient alc. oxidn. catalysts that mimic the enzyme galactose oxidase. Different ligand substitutions were explored based on natural (copper, depicted) and alternative (rhodium) metal redox centers. ...

Self-field effects in NbTi subsize cable-in-conduit conductors

Pierluigi Bruzzone, Boris Stepanov, Rainer Wesche, Martin Vogel

In the framework of the conductor optimisation task (CONDOPT) five NbTi subsize cable-in-conduit conductors with parametric variations were fabricated. The DC performance of these conductors tested in the SULTAN test facility [IEEE Trans. Appl. Supercond. ...

Mitigation of Lightning-Induced Overvoltages in Medium Voltage Distribution Lines by Means of Periodical Grounding of Shielding Wires and of Surge Arresters: Modeling and Experimental Validation

Mario Paolone, Carlo Alberto Nucci, Emanuel Petrache

In this paper, we investigate the effect of periodically-grounded shielding wires and surge arresters on the attenuation of lightning-induced voltages. We discuss the adequacy of the commonly made simplification of assuming the shielding wire at ground pot ...

Self field measurements by hall sensors on the SeCRETS short sample CICC's subjected to cyclic load

Pierluigi Bruzzone

An imbalance in the transport current among the strands of a Cable-in-Conduit conductors (CICC) can be associated with the change of their performance. In order to understand and improve the performance of CICC's, it is essential to study the current imbal ...

The voltage/current characteristic (n index) of the cable-in-conduit conductors for fusion

Pierluigi Bruzzone, Boris Stepanov, Rainer Wesche

The index n of the voltage-current characteristic of large superconductors is a crucial parameter to assess the allowed range for coil operation. In the tests of the Insert coils at the CSMC as well as in the short sample test in the SULTAN facility, it is ...

Test results and analyses of conductor short samples for HT-7U

Pierluigi Bruzzone, Jiannong Fang, Boris Stepanov, Jie Chen, Bo Li

The experiments of Cable-in conduit conductor (CICC) short samples with high proportion of segregated copper strands have been carried out in SULTAN facility last September. These experiments aimed to investigate transient stability and AC losses of CICC c ...

Finite element method analysis of the coupling effect between superconducting filaments of different aspect ratio

Francesco Grilli, Yong Yang, Bertrand Dutoit

Using 3D finite element method (FEM) modelling, the present work investigates the coupling effect between two finite superconductors through a resistive matrix. This effect, related to the finite length of the conductors, is typically three-dimensional and ...
