  • n-Values of commercial YBCO tapes before and after irradiation by fast neutrons 
    Chudy, Michal; Zhong, Z.; Eisterer, M.; Coombs, Tim (IOP Publishing Limited, 2015-01)
    The n-value is an important superconducting parameter, which represents the homogeneity of characterized superconductor as well as thermally activated depinning. In addition n-values are important for the evaluation of ...
  • Power losses of 2 G HTS coils measured in external magnetic DC and ripple fields 
    Chudy, Michal; Chen, Yiran; Zhang, Min; Baghdadi, Mehdi; Lalk, Jorg; Pretorius, Tinus; Coombs, Tim (IEEE / Institute of Electrical and Electronics Engineers Incorporated, 2014-02)
    Power losses are an important phenomenon in 2nd type superconductors. Precise evaluation of power losses in superconducting coils is crucial for the design of novel machines such as superconducting motors or generators. ...
