| Tepelná stabilita supravodivých cievok a filamentovaných REBCO pások | |
| Thermal stability of superconducting coils and filamentized REBCO tapes | |
| Program: | VEGA |
| Project leader: | Mgr. Seiler Eugen, PhD |
| Annotation: | The project investigates electro-thermal stability of filamentized superconducting REBCO tapes andsuperconducting coils at transporting the electric current. The goal is to develop theoretical models and numericalmethods allowing to determine the maximum transport current that can flow through a superconducting coil orthrough a filamentized tape without the risk of a rapid local heating. Characterization of tapes and coils will bebased on the standard measurement methods as well as on specially designed experiments, which will allow toincorporate the real parameters of available superconducting tapes into the models. In order to experimentallyverify the theoretical models of thermal stability of superconducting coils, specific model coils will be built,equipped with multiple voltage and temperature sensors for detailed monitoring of the electro-thermal stability.The outcomes of the theoretical models will subsequently be applied at manufacturing bigger coils, relevant forrealistic electric devices. |

| Nízkostratový supravodivý kábel typu CORC z REBCO vodičov | |
| Low-loss superconducting CORC-like cable from REBCO conductors | |
| Program: | VEGA |
| Project leader: | Mgr. Seiler Eugen, PhD |
| Annotation: | Aim of the project is to elaborate the design of a superconducting CORC-like cable with considerably reduced AClosses. Project is focused on identification of the key parameters of the cable design, on the construction of modelcables and their experimental characterisation. The research will follow two basic directions: optimisation ofgeometrical layout of the individual REBCO tapes in the cable and investigation of possible utilisation of lowconductivity materials for the central core of the cable. Geometrical optimisation of the cable will be based onresults of numerical simulations employing the Finite Element Method and the Minimum Electro-Magnetic EntropyProduction method. In the experimental part, sets of short model cables will be manufactured for tests of differentgeometrical configurations and different materials for the central core. Investigated will be the total AC losses,basic transport parameters and degradation of superconducting tapes due to mechanical loading in the cablingprocess. |
