Stockholm-Uppsala Centre for Free Electron Laser Research

In March 2006, the Royal Institute of Technology (KTH), Stockholm University (SU) and Uppsala University (UU) established a common Centre for Free Electron Laser Research, organizationally tied to Stockholm University and the Manne Siegbahn Laboratory.

The primary goal of the centre is to make the three universities active and visible partners in research at and development of advanced free electron laser (FEL) facilities.

A secondary goal is to increase the competence for advanced FEL-related scientific and technical activities within KTH, SU and UU in order to facilitate possible future opportunities to provide Mälardalen with free electron lasers or possibly other types of advanced light sources as motivated by the scientific needs of this influential and forceful university region.

A letter of intent concerning collaboration on technical and scientific developments for research using free electron lasers was signed with DESY, Hamburg, in 2004, and parts of several workpackages for the development of the European XFEL at DESY have since then been taken on by the partners in the FEL Centre.

The Manne Siegbahn Laboratory has made a feasibility study on the use of permanent-magnet/electromagnet hybrid dipole magnets for the deflection of the spent XFEL electron beam behind the undulators. MSL will also work on the characterization and fiducialization of quadrupole magnets for the XFEL undulators.

Status report on characterization and fiducialization:

The feasibility study is available here:

  1. Investigating the possibility of a hybrid magnet design for BV/BW dipole magnets at the XFEL
  2. Comparison of two hybrid magnet designs
  3. Neutron radiation damage study and cost estimate of a hybrid magnet for the XFEL
