dr.ir. A.U. Kario (Anna)

I am a scientist in Applied Physics Engineering interested in front line research on superconductivity. I am especially passionate about practical superconductors for enabling advanced magnet technology and the associated magnet design, modelling, engineering and testing.

My journey with superconductivity started with work on materials like MgB₂ and continued with applied superconductivity, developing materials, building demonstrators using mostly REBCO HTS superconductor. I took part in development of high-current superconducting cables for future fusion magnets, energy transport application, and for use as low AC loss superconductor.

I led the development of the so-called high-temperature superconducting REBCO Roebel cables in frame of European project (EuCARD2) which lead to the first REBCO tape based accelerator demonstrator dipole magnet constructed and successfully tested at CERN.

I was involved in magnet testing for the so-called Quadrupole Doublet Module integration at FAIR. Where I gained a lot of experience in supervision of industry and research institutes preparing the magnet test station and all related matters. Through this project, I further developed my knowledge of cryogenics, beam instrumentation and associated accelerator technologies.

At Energy Materials and Systems cluster I am leading the research line towards future high field accelerator magnets. In this research line we are investigating Nb₃Sn training issues in frame of collaboration with Paul Scherrer Institute in Switzerland. We are interested in mechanical properties of HTS, as BSCCO and REBCO systems, since those are enabling fields of 20T+. Beside superconducting properties of various systems, we are looking at impregnation solutions, which is crucial for magnet technology. We work together with CERN (CERN), Paul Scherrer Institute (PSI), Lawrence Berkeley National Laboratory (LBNL), National High Magnetic Field Laboratory (MagLab) and CEA Saclay (CEA) investigating above mentioning research topics.
