About Me

            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.

At Energy Materials and Systems cluster I am leading the research towards future high field accelerator magnets of 20T+. We are investigating Nb3Sn training issues in frame of collaboration with Paul Scherrer Institute in Switzerland in BOX program (EMS Team: Simon Otten, Jan van Steenlandt). We are interested in mechanical properties of High Temperature Superconductors, as BSCCO-2212 and REBCO systems, looking especially at transverse stress behavior (EMS Team: Simon Otten, Sander Wessel). On demonstrator level we are interested in ReBCO pancake coils inserts behavior in external magnetic field up to 8 T (EMS Team: Thomas Nes, Jeroen Boerma, Sander Wessel, Jorick Leferink). Last but not least we take part in muon collider initiative with contribution to challenging ultra-high magnetic fields up to 50-60T (EMS Team: Simon Otten, Herman ten Kate).

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.
