Peter Willendrup, Development engineer,  RISØ DTU, Materials Research DivisionScandinavia was highly represented at the ICNS meeting in Knoxville, Tennessee. Scandinavian scientists gave three invited talks and several (8) oral contributions, not counting many posters. In total, 30 contributions were presented by scientists affiliated in Scandinavia, which is a very large number compared to other countries, but reflects the expertise and experience of Scandinavia in the field of neutron research. Moreover, a parallel one-day workshop on neutron instrument simulation was organised by McStas experts from Copenhagen and Risø (and ILL!) where neutron scientists could get some training in instrument modeling.

This does not come as a surprise since the neutron community in Scandinavia has developed neutron science for decades through the research carried out at the facilities for neutron scattering in Denmark, Sweden and Norway.

  • In Denmark, Risø National Laboratory (now Risø DTU) has an outstanding international reputation in neutron diffraction and neutron scattering research and has been developed over the years thanks to their reactor-based neutron facility. Risø has had a seminal role in neutron methods and has had an impact on all neutron instruments. All the expertise acquired there has been passed on to other neutron centres in the world, in particular SINQ at PSI, Switzerland, where Danish scientists are operating several instruments.
  • In Sweden, scientists are using neutron scattering methods in soft condensed matter, in physics and chemistry in engineering sciences; they work at the ILL, Grenoble, at ISIS in UK, at PSI in Switzerland, but also in Germany. In Sweden, experiments were performed at the Swedish research reactor R2 in Studsvik. The NFL - Studsvik Neutron Research Laboratory was a leading institute for neutron sciences. As a company, Studsvik operates not only in Sweden, but also in UK, Germany or USA and has a further company segment for Global Services.
  • In Norway, the research reactor JEEP II at Kjeller (Institute for Energy Technology, IFE, near Oslo) is a national resource for material physics research and neutron irradiation technology. The availability of this multi-purpose reactor is kept very high to content the many user-groups.

All these centres have joined forces to develop modeling tools to optimise various neutron instruments, which explains why the Copenhagen / Roskilde group is acquired such high repute in neutron instrument modeling and virtual experiments run on computers.

As a complement to the international organisation now being built up by ESS Scandinavia for designing and developing the accelerator driven, next generation neutron source in Sweden; the 273 neutron users in Scandinavia will provide us with a solid base of supporting expertise right in the neighbourhoods of Lund!
