The attention of the fusion magnet specialists has been drawn in the last years to the volt-ampere characteristic (VAC) of the large cable-in-conduit conductors (CICC), as early voltage was observed in conductor and model coil tests, far away from the expe ...
Recent International Thermonuclear Experimental Reactor (ITER) Model Coils and tests on Nb-3 So Cable in Conduit Conductors (CICC) showed a significant and unexpected increase in the broadness of the transition to the normal state, resulting in degradation ...
Current reconstruction in cable-in-conduit conductors (CICC) cables is a crucial issue to determine cables performance in working conditions, and must be performed using inverse problem approaches as direct measurement is not feasible. The current distribu ...
The aim of this paper is to provide an overview of a recent study carried out-within the framework of the European Fusion Program-to design a 12.5 T superconducting dipole. By focusing on the CICC based design option, the overall design procedure is presen ...
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 ...
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 " ...
An imbalance in the transport current among the strands of a Cable-in-Conduit conductors (CICC) can be associated with the change of their performance. In order to understand and improve the performance of CICC's, it is essential to study the current imbal ...
Transient stability experiments are carried out on a Nb3Sn cable-in-conduit conductor in the SULTAN test facility. A disturbance of variable duration is applied by a pulsed field, transverse to the conductor axis. The results show a high tolerance to large ...
A high order finite difference scheme is introduced to deal with thermo-hydraulic quench simulation in superconducting magnets, specifically in the case of cable-in-conduit conductors (CICC). Liquid helium flow in CICC is governed by the unsteady convectio ...
The experiments of Cable-in conduit conductor (CICC) short samples with high proportion of segregated copper strands have been carried out in SULTAN facility last September. These experiments aimed to investigate transient stability and AC losses of CICC c ...
