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 ...

Computations of AC loss in the ITER magnets, during fast field transients

Jonathan Bryan Lister, Pierluigi Bruzzone, Luca Bottura

The calculation of AC loss due to the control currents in ITER is a cumbersome task. The reason is that control transients require small field changes (0.1 T or less) at moderate frequency (up to 10 Hz), where effects of partial penetration of the filament ...

Assessment of the effect of current non-uniformity on the ITER Nb3Sn good joint short sample DC performance

Pierluigi Bruzzone

The DC performance of the so-called Good Joint Nb3Sn Short Sample conductor, measured in the SULTAN facility in 1999 with a progressively reduced (chopped) joint length, became worse as the joint became shorter. In this paper we present the analysis of tho ...

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 ...

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 " ...
