Irreversible Degradation in Nb3Sn Cable in Conduit Conductors

One of the biggest goals for the international thermonuclear experimental reactor (ITER) is the steady state operation. For this reason all its coils will be superconducting and Nb3Sn material is used for both the toroidal field (TF) and the central soleno ...

Testing of RF 100 m TF Qualification Conductor in the SULTAN Test Facility

Pierluigi Bruzzone, Boris Stepanov

A conductor for ITER toroidal field (TF) coils is the cable-in-conduit conductor (CICC) type, which is made of Nb3Sn superconducting strands encased in a stainless steel tubular jacket. A 120-m-long prototype has been designed in accordance with ITER requi ...

Manufacture of ITER feeder sample conductors

Pierluigi Bruzzone, Bo Liu, Hongwei Li

The ITER feeders are the components that connect the ITER magnet systems located inside the main cryostat to the cryogenics, power-supply and control system interfaces outside the cryostat. The feeder busbars rely on the Cable-In-Conduit Conductor (CICC) d ...

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

Pierluigi Bruzzone, Davide Uglietti, Boris Stepanov, Ciro Calzolaio

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, ...

Measurement of Tc distribution in NbSn CICC

Pierluigi Bruzzone, Davide Uglietti, Ciro Calzolaio

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 ...

Dependence of the ac loss on the aspect ratio in a cable in conduit conductor

Pierluigi Bruzzone

The coupling current loss in rectangular superconducting cables is strictly dependent on their aspect ratio, which has an impact on the area linked by the field variation and consequently on the currents induced between strands. The relation between the ac ...

Test results of two ITER TF conductor short samples using high current density Nb3Sn strands

Pierluigi Bruzzone, Boris Stepanov, Rainer Wesche

Two short length samples have been prepared and tested in SULTAN to benchmark the performance of high current density, advanced Nb3Sn strands in the large cable-in-conduit conductors (CICC) for ITER. The cable pattern and jacket layout were identical to th ...

Conceptual design of the 12.5 T superconducting EFDA dipole

Pierluigi Bruzzone

Within the framework of the European Fusion Programme (EFDA) a design activity has been started in late 2004 by the EFDA Close Support Unit at Garching (FRG) to design a 12.5 T superconducting dipole magnet. The final goal of this activity is to define a " ...
