Progresses and challenges in the development of high-field solenoidal magnets based on RE123 coated conductors

Recent progresses in the second generation REBa2Cu3O7-x (RE123) coated conductor (CC) have paved a way for the development of superconducting solenoids capable of generating fields well above 23.5 T, i.e. the limit of NbTi-Nb3Sn-based magnets. However, the ...

Commissioning of the Main Coil of the EDIPO Test Facility

Rainer Wesche, Pierluigi Bruzzone, Boris Stepanov, Martin Vogel, Markus Jenni, Giancarlo Croari, Stephen Alfred March, Davide Uglietti

The EDIPO test facility is erected at CRPP Villigen with the aim of providing a flexible, high field test bed for high current force flow superconductors. The EDIPO main coil is a tilted-head race-track pair wound by a graded Nb3Sn cable-in-conduit conduct ...

MgB2 Hollow Wires and Cables Embedded in a Mg Alloy Matrix

Pierluigi Bruzzone, Davide Uglietti

The brittleness of the MgB2 wires prevents performing a cable architecture with very small bending radius, similar to NbTi Rutherford cables. Consequently, it is important to reduce the thickness of the superconducting materials in order to increase its be ...

Prospects for the use of high-T-c superconductors in fusion magnets and options for their test in SULTAN

Rainer Wesche, Pierluigi Bruzzone, Boris Stepanov, Stephen Alfred March, Davide Uglietti

In the last few years, the critical current densities of long commercially available REBa2Cu3O7-x (RE-123, where RE represents Y or a rare earth element) coated conductors have reached values of 250 A/cm-width at 77K and zero applied field. Even higher val ...

Effect of transverse load on the critical current of a coated conductor Roebel cable

Rainer Wesche, Pierluigi Bruzzone, Davide Uglietti

Roebel cables are one possible option for use in the manufacture of high current conductors for various technical applications. In this work the behaviour of critical current under transverse loads up to 90 MPa was studied in coated conductor Roebel cables ...

Fabrication Trials of Round Strands Composed of Coated Conductor Tapes

Rainer Wesche, Pierluigi Bruzzone, Davide Uglietti

Various techniques have been proposed in order to assemble coated conductor tapes into high current strands. In this work, the preparation of high current capacity round strands starting from industrial coated conductors has been investigated. Round, twist ...

In situ Tc measurements of cable in conduit conductors via an inductive method

Pierluigi Bruzzone, Boris Stepanov, Ciro Calzolaio, Davide Uglietti

The measurement of the actual thermal strain, epsilon th, in a cable in conduit conductor (CICC) of Nb3Sn is of paramount importance to predict the CICC performance in operation starting from the strand scaling laws for the critical current density J(c)(B, ...

Statistical analysis of the current-sharing temperature evolution in Nb3Sn cable-in-conduit-conductors for ITER

Rainer Wesche, Pierluigi Bruzzone, Boris Stepanov, Davide Uglietti

During the test of ITER conductors at nominal conditions, a degradation of the current sharing temperature has been observed after electromagnetic cyclic loading. Rather than focusing on the microscopic phenomena at the origin of the degradation, the degra ...

Measurement of Tc distribution in NbSn CICC

Pierluigi Bruzzone, Ciro Calzolaio, Davide Uglietti

Knowledge of the actual Nb3Sn filaments' thermal strain, epsilon(th), in a cable-in-conduit conductor (CICC) is essential to predict the CICC performance in operation starting from the strand scaling laws for the critical current density J(c)(B, T, epsilon ...

Development of magnet technologies for HTS insert coils

Rainer Wesche, Pierluigi Bruzzone, Boris Stepanov, Stephen Alfred March, Davide Uglietti, Natalia Hanna Glowa

An existing Nb3Sn laboratory magnet generating a magnetic field of 12 T is intended to be upgraded to 16 T by means of the use of a high temperature superconductor (HTS) insert coil. An outline design of the HTS insert coil is presented. In the design, the ...

Design of a quench protection system for a coated conductor insert coil

Davide Uglietti

Coated conductors are promising material for the construction of high field magnets, but the slow propagation velocity of the normal zone makes the protection against quenches a critical issue. The quench protection system for a small insert coil under dev ...

Correlation between the overall T-c distribution in Bronze Route Nb3Sn wires and the Sn gradients in the filaments

Davide Uglietti

From specific heat measurements of Ta + Ti alloyed Bronze Route multifilamentary Nb3Sn wires, a wide, nearly symmetric overall distribution of T-c can be determined. This is apparently in contradiction with the almost linear decrease of the Sn content towa ...

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 ...
