Overview of the Felix facility
Connection between the Felix Facility and High Field Magnet Laboratory

Radboud University Nijmegen was established in 1923. It has currently seven faculties and enrols over 20.000 students. It is a student-oriented research university. The Faculty of Science at Radboud University operates the FELIX Laboratory and the High Field Magnet Laboratory (HFML), both open-access, large-scale research infrastructures, and has a number of research faciltities such as the NMR laboratory, NanoLab and Trace Gas Facility on campus. The FELIX Laboratory is scientifically embedded in the Institute for Molecules and Materials and focuses on the development and exploitation of Free Electron Laser sources in the infrared and THz regime. It comprises several research groups with complementary expertise such as (bio)molecular physics, solid state physics and soft condensed matter specialized in research with infrared and THz FEL radiation.

Excellence: The FEL-based User Facility FELIX provides unique experimental capabilities by its infrared beam lines FLARE, FEL-1 and FEL-2 operating in the wavelength range 3-1500 µm and the intra-cavity laser FELICE operating between 3-100 µm. The FLARE and FELIX beam lines are coupled to 15 user laboratories covering sophisticated instrumentation for experiments in the areas of molecular and biomolecular spectroscopy, cluster sciences, time-resolved spectroscopy, laser spectroscopy. World-unique is the combination of the infrared and THz radiation with the magnets (up to 38 T dc magnetic field) of the HFML.
