Emerging neutron and X-ray facilities: ESS, MAX-IV, and X-FEL

The group is deeply involved in a number of activities related to the two facilities in Lund (S): The emerging neutron facility, the European Spallation Source (ESS), and its neighbour functional X-ray facility, MAX-IV; and the European Free Electron X-ray Laser (XFEL) in Hamburg (D).

- Building and design of instruments for ESS. Denmark, Norway, and Switzerland have joined forces to build 2 instruments for ESS: BIFROST and HEIMDAL. We are also involved in the construction of the MIRACLES instrument. Recently, we have been involved in the design of further instruments, KVASIR, THOR, and SIF, to be proposed for the next round of ESS.

- Simulation of instruments for ESS using the simulation package McStas. Kim Lefmann is leading the NBI group of McStas instrument simulations, helping instrument designers at ESS in Lund.

- Jacob Kirkensgaard is chair and Kim Lefmann a board member of the University of Copenhagen X-ray and Neutron Science Network and Heloisa Bordallo is board member of ISBUC - both networks aiming to strengthen cross-displinary collaboration and help new users of X-ray and neutron methods. Jacob Kirkensgaard is also involved in a Halric project with Malmö University and MAXIV with focus on rheo-SAXS methods. Jacob Kirkensgaard is PI on the new ESS Lighthouse CaIFF

- Educating for the new facilities. The group runs one specialized course in X-ray scattering (Heloisa Bordallo and Jacob Kirkensgaard) and one in neutron scattering (Kim Lefmann); both are mixed theory/lab courses. See SIS pages under Physics m.sc. education. In addition, one common X-ray-neutron course is held as a summer course (3 weeks in August) for m.sc. students with a general science background (Heloisa Bordallo).

Also, Jacob Kirkensgaard is host for annual PhD school in Small-Angle Scattering." and Kim Lefmann leads the annual Nordic Neutron Scattering School, a course for introductory PhD students from the Nordic countries.

- Expert advice to the Danish Ministry of Education, Kim Lefmann is vice chair of DANSCATT, which is both the national instrument center for X-ray and neutron users, and the national advisory board for related strategic policies.

- Through DANSCATT, the group have access to international synchrotron and neutron facilities, including

- Neutron user organizations, Kim Lefmann leads the Danish Neutron Scattering Society, DANSSK, which is organized as a committee under DanScatt. He is also board member of the European Neutron Scattering Association, ENSA. 

Jacob Kirkensgaard is the Danish representative in the steering group of the Nordic Scattering from Soft Matter committee.
