The infrared user facility FELIX



Starting March 2012 the FELIX facility will move to the Radboud University Nijmegen to merge with the free-electron laser FLARE currently being commissioned.


The user facility comprises three different beamlines. Two beamlines, FEL1 and FEL2, provide continuously tunable radiation in the spectral range of 2500-40 cm-1 (4-250 mm, 1.2-75 THz) peak powers ranging up to 100 MW in (sub)picosecond pulses, and is being used for scientific research in (bio-)medicine, (bio-)chemistry and (bio-)physics. The third beamline, FELICE, is devoted to intra-cavity experiments on gas phase (bio-)molecules/ions, clusters and complexes. It provides continuously tunable radiation in the spectral range of 2000-250 cm-1 (5-40 mm) and the infrared intensity available to the experiment is a factor of up to a hundred increased compared to FELIX.


The next call for proposal will be launched as soon as regular, reliable user operation is possible again.


  •   First users experiments are expected to be possible in the fall of 2013 although restrictions in the wavelength range, the experimental setups available etc. may apply.
