NESPA – Nanotechnologicky upravené supravodiče pre aplikácie v silnoprúdovej elektrotechnike
Nano-Engineering Superconductors for Applications – European Network
Program: FP6
Project leader: doc. Ing. Gömöry Fedor DrSc.
Annotation: The project will focus on the most promising superconducting materials, preparation techniques, applications and cryogenic developments for the envisaged power application systems. Therefore, the materials research topics will be restricted to RE123 coated conductors, RE123 bulk material and MgB2 wires and tapes. There, improving the critical current density as the central figure of merit of superconducting materials for power applications requires the controlled incorporation of a high density of nano-scale defects into an undisturbed crystalline matrix. The electrical engineering issues under consideration will concentrate on reducing ac-losses in superconducting wires and tapes by innovative conductor designs with micrometer scaled structures in the superconductor, which can only be realized by means of material processing in the nanometer scale. The industrial aspects are focused on scale-up the material preparation and the realization of superconducting cables, motors, magnets and the cryogenics involved.

HIPERMAG – Nano a mikro technologické postupy pre výkonné MgB2 kompozitné supravodiče na veľké aplikácie
Nano – and micro – scale engineering of higher – performance MgB2 composite superconductors for macro – scale applications
Program: FP6
Project leader: Ing. Kováč Pavol DrSc.
Annotation: HIPERMAG aims to fuse existing research efforts of individual partners into a cencerted European RTD activity. The project objective is to overcome these two bottlenecks in material performance by developing scaleable nano- and micro-engineering processes for optimised MgB2 powders and wires. In three years time, these processes will be ready for transfer to industrial production and commercialisation of high-performance, low-cost MgB2 conductors.

Pokrokový MgB2 supravodič bez difúznej bariéry
Advanced MgB2 superconductor without diffusion barrier
Program: VEGA
Project leader: Ing. Kováč Pavol DrSc.
Annotation: The essence of the project is to prepare and optimize the method of preparation of superconducting composite wire (filaments) by the method of magnesium infiltration or diffusion into boron. The main emphasis will be focused on the simplicity of preparation (without the diffusion barrier), the availability and suitability of the sheath materials and their electro-mechanical properties. The properties of the MgB2 superconducting core will be controlled by technological preparation, annealing conditions, and possible doping. Selection of suitable materials and technological processes allows monitoring of effects on micro-structure, mechanical properties and superconductive properties: critical current density at temperatures in the range of 4.2 – 20 K, critical temperature, connectivity or losses in alternating magnetic field. The role of the project will be also to examine the possibility of creating superconducting links.

Superconducting coils made of uniform MgB2 wires with tubular filaments
Program: SRDA
Project leader: Ing. Kováč Pavol DrSc.
Annotation: The aim of this project is to develop the process of infiltration/diffusion (IMD) for long and uniform superconducting wires with tubular MgB2 filaments resulting in high engineering current densities measured in coils cooled by solid nitrogen in persistent mode. The main aim is to increase three times the engineering current density in long IMD MgB2 wires in comparison to those commercially obtained by powder-in-tube (PIT) process, especially in the range of magnetic fields 1-5T and temperatures around 20K

Kompozitný supravodič MgB2 na báze difúznej metódy
Composite superconductor MgB2 made by internal Mg diffusion
Program: VEGA
Project leader: Ing. Kováč Pavol DrSc.
Annotation: The goal of this project is to prepare superconducting wire (filament) using new method of diffusion of magnesium (IMD) into the boron layer. The usability of this method is regarded by resulting very high density of superconducting part in the composite. One of the purpose is to optimize the IMD technique in that way, that dense MgB2 wire reach very high critical current density Jc comparing to older techniques (ex situ, in situ). We can expect improvement of important technical parameters like critical current density in low magnetic fields (< 3 Tesla) and critical temperature to be competitive also for low temperature superconductors (Nb3Sn, NbTi, Nb3Al …), having another advantage of more efficient cooling technique without the liquid helium.
