Lunds universitet, Naturvetenskapliga fakulteten, MAX N-fak

Lund University was founded in 1666 and is repeatedly ranked among the world’s top 100 universities. The University has 40 000 students and 7 600 staff based in Lund, Helsingborg and Malmö. We are united in our efforts to understand, explain and improve our world and the human condition.

The Faculty of Science conducts research and education within Biology, Astronomy, Physics, Geosciences, Chemistry, Mathematics and Environmental Sciences. The Faculty is organized into nine departments, gathered in the northern campus area. The Faculty has approximately 1500 students, 330 PhD students and 700 employees.

The Department of Physics is with a staff of about 350 scientists and educators one of the largest departments within Lund University. There are seven research divisions and a number of research centra within the department. The research activities at the department cover a broad spectrum of modern physics.

The SXL project
The SXL (Soft X-ray Laser) project is a project for a Free Electron Laser in the soft X-ray energy range at the MAX IV facility at Lund University. A design study has recently been funded and will be completed in the coming two years. The funding comes from the Knut & Alice Wallenberg foundation and several Swedish universities. The SXL will be based on the 3 GeV linac already in operation at the MAX IV.

The Post doc position is placed at the Science Faculty at Lund University. The FEL modeling of the SXL is led by Ass. Prof. Francesca Curbis and the group’s work towards the SXL project is co-ordinated by Prof. Sverker Werin.

Depending on additional funding the announced position may be expanded to two positions.

The main task will be setting up and performing FEL simulations for the SXL project. The baseline design provides a parameter space that needs to be investigated. In a first step a thorough study of the optics and definition of matching lattice followed by time independent simulations with a 3D FEL code (Genesis or similar) should be performed.

In the second part of the period, start-to-end simulations should be implemented and the postdoc task will be central in the connection between linac simulations and FEL simulations and in order to perform a sensitivity study also with photo-cathode gun simulations. The tasks will possibly also include studies and development of advanced FEL pulse shaping and optimization, as concepts and/or full simulations.  

The project may also include measurements on the existing accelerator to verify the accelerator modeling.

The successful candidate should have a thorough experience of FEL simulations and modeling. The suitable postdoc should be able to both work alone and to collaborate with the other persons in the team. Ability to discuss and share knowledge and results is crucial for building the overall competence in the project. Creativity and ability to discuss and jointly develop the second phase of the SXL with advanced features for the FEL will be crucial.


  • A PhD in FEL physics, accelerator physics or equivalent subject.
  • Experience and good knowledge of FEL simulations (including time-dependent simulations).
  • Knowledge of and ability to model and analyze accelerator systems.
  • Very good knowledge of English.
  • Experience of FEL and accelerator operation is an advantage.
  • Experience from previous FEL design studies is an advantage.
