The Forschungszentrum Karlsruhe (FZK) and the Centre de Recherches en Physique des Plasmas (CRPP) are working on a joint development program to construct and test a 70 kA current lead using High Temperature Superconductors (HTS) for the Toroidal Field (TF) ...
In the frame of the European Fusion Technology Programme, the Forschungszentrum Karlsruhe (FZK) and the Centre de Recherches en Physique des Plasmas (CRPP) are developing a 70 kA current lead for the toroidal field coils of the International Thermonuclear ...
A 40 kA Nb3Sn conductor, designed to operate with forced helium flow at 4.5 K was tested in the SULTAN III facility, (I(max) = 50kA, B(max) (background) = 11T). The test sample and the operating conditions of the test facility are described. Two measuremen ...
SULTAN, the world wide unique, high field, large bore test facility. has been built as European contribution to the development program for ITER, The facility has primarily been devoted to the qualification of full-size cable-in-conduit-conductors (CICC) f ...
The reduction of static heat load in superconducting magnet systems is of great importance because of reduction of refrigeration power and operational costs. The major elements that determine the heat load are the current leads. The use of high temperature ...
The toroidal Field Conductor Insert (TFCI) coil was tested at 46 kA in the 13 T background magnetic field generated by the Central Solenoid Model Coil. The single layer TFCI coil uses a Nb3Sn cable-in-conduit conductor in a Titanium jacket. The object of t ...
Measurements of Ag/Bi(2223) superconducting tapes have been performed between dc and 30 KHz for under and upper critical currents, up to 2 or 3 times i(c). A fast power amplifier (100A 30KHz) has been specially built for pulsing such currents in the sample ...
For describing the E-J relation of high-Tc superconductors (HTS) in power applications, where the applied current I is generally limited by Ic, the critical state model, a piecewise linear generalization, or a simple power-law of the type E=Ec(J/Jc)^n are ...
