Analysis of DC properties and current distribution in TFAS ITER conductor samples using high J(C) Nb3Sn advanced strands

Pierluigi Bruzzone, Boris Stepanov

Two full-size conductor samples using advanced Nb3Sn strands were tested in the SULTAN facility in 2005-2006 within (I,B,T) ranges close to the ITER operating conditions (B-MAX similar to 12 T, T similar to 5 K). Each sample includes two conductor legs, co ...

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

Rainer Wesche, Pierluigi Bruzzone, Boris Stepanov, 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 ...

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

Rainer Wesche, Pierluigi Bruzzone, Boris Stepanov

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 ...

Test results of a small size CICC with advanced Nb3Sn strands

Rainer Wesche, Pierluigi Bruzzone, Boris Stepanov

In the scope of the design activities for a 12.5 T dipole magnet, a short length of cable-in-conduit conductor (CICC) with steel jacket was prepared in spring 2005 as a pre-prototype of the high field dipole conductor. The small, rectangular conductor uses ...

A critical review of coupling loss results for cable-in-conduit conductors

Pierluigi Bruzzone, Boris Stepanov

AC loss curves measured for the same conductors at SULTAN (CRPP) and at University of Twente (UT) in higher and respectively lower frequency range are compared to draw consistent results. From the unified curves, the coupling time constant (n tau) to be us ...
