This Ph.D. thesis is focused on the development of novel models for calculation of AC losses, current and magnetic field profiles in high-temperature superconductors (HTS). The thesis is concentrated on the modelling of Bi-2223 conductors at 77 K, which fo ...
Prototype conductors for the ITER magnets have been tested extensively in the SULTAN facility at CRPP in the last decade. The in-depth characterization of the high current carrying conductors provided a valuable feedback in the design, with performance opt ...
This paper presents results from numerical modeling of non-twisted multifilamentary Bi-2223/Ag conductors with various geometry and filament arrangement. Anisotropic models of Jc(B) and n(B) have been employed in finite element method simulations under dif ...
In recent years, power variations and energy criteria have been the main motivations for developing regenerative drive converters for elevators [1]. A better performing solution for power smoothing can be easily found by using a supercapacitor-based storag ...
Two subsize, Nb3Sn cable-in-conduit conductors, are tested as short samples in the SULTAN test facility. Transverse load is applied by sweeping up and down the operating current in high background field. A serious performance loss of I, and n-factor is obs ...
L-mode to H-mode (LH) transitions are observed in a large variety of plasma conditions in TCV Ohmic plasmas. The power flowing through the separatrix at the LH transition differs by up to a factor of two from the predicted H-mode threshold power. Variation ...
In recent years, power variations and energy criteria has been the main motivation for developing regenerative drive converters for elevators [1]. A more performant solution for power-smoothing can be easily found by using a supercapacitor based storage de ...
In certain power applications, Bi-2223 conductors carrying AC current will be subjected to external magnetic fields, whose orientation and conductor’s geometry are of major significance for the AC loss magnitude. This paper investigates the influence of th ...
Mono and multifilamentary HTS tapes exhibit non-negligible AC loss in self-field and considerably higher losses in the presence of external magnetic field. The effect of the conductor’s geometry on the AC loss has been investigated in this paper. The nonli ...
