Predictive analysis of the ITER Poloidal Field Conductor Insert (PFCI) test program

Rainer Wesche, Kyungjin Kim

In this paper we discuss the predictive analysis performed in support of the test program of the International Thermonuclear Experimental Reactor (ITER) Poloidal Field Conductor Insert (PFCI). A subset of the test program items was considered, with particu ...

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 ...

70 kA high temperature superconductor current lead operation at 80 K

Rainer Wesche

For the superconducting magnet system of the International Thermonuclear Experimental Reactor, ITER, 60 current leads for a total current of more than 2500 kA are needed. To reduce the resultant large refrigerator load at 4.5 K, High Temperature Supercondu ...

Comparison of the DC performance of full- and sub-size NbTi cable-in-conduit conductors

Rainer Wesche, Pierluigi Bruzzone, Boris Stepanov

The DC performances of three full- and five sub-size NbTi cable-in-conduit conductors, measured in the SULTAN test facility, are compared. In general, the self-field effect was found to cause sudden take-offs at high currents. In most of the investigated c ...
