The effect of compaction of ex-situ MgB2-powder, i.e. cold and hot uniaxial pressing, Spark Plasma Sintering (SPS) and of a post annealing on microstructure and superconducting properties of ex-situ bulk samples is studied. Additionally the impact of

We present a new high-deposition-rate coating technique that allows us to produce at room temperature long thick films of MgB 2 on flexible steel substrates. Such a technique might give rise to new tapes with higher filling factors compared to the st

We investigate the use of 2nd-generation High-Temperature Superconductors (2G-HTSs) in the rotors of electrical motors and generators. For these devices the conductor must be wound into robust impregnated coils, which are operated in vacuum at temper

We have manufactured and tested new HTS coil configurations in order to extend the range of rotating machines to which HTS tapes can be applied. The rotors of large utility generators require operating currents of several kA, which can be achieved by

Future magnetic-resonance imaging (MRI) systems for medical diagnosis may work on the principle of pre-polarization. This requires a strong local magnetic field which can be ramped up and down in milliseconds. Such fields can be generated efficiently

A reliable method for persistent-current mode operation of HTS magnets is still not available. As an alternative solution to external high-current power supplies we have developed a cryogen-free operating transformer-rectifier type HTS flux pump. Usi

High-temperature superconducting (HTS) transformers and reactor coils promise decreased weight and volume and higher efficiency. A critical design parameter for such devices is the AC loss in the conductor. The state of the art for AC-loss reduction
