The radiation source ELBE at the Helmholtz-Zentrum Dresden-Rossendorf (former Forschungszentrum Dresden-Rossendorf (FZD)) is built around a superconducting electron linear accelerator, constructed to produce quasi cw electron beams up to 1 mA beam current at 12 - 34 MeV. The electron beam is used to generate various kinds of secondary radiation, mainly to drive the two free-electron lasers U27 and U100 in the infrared region (4-250 μm). Starting in summer 2005 user beam time is offered to external users in the frame of the EC funded “Integrating Activity on Synchrotron and Free Electron Laser Science” (FELBE project). FELBE is an acronym for the free-electron laser (FEL) at the Electron Linear accelerator with high Brilliance and Low Emittance (ELBE). Twice a year users are invited to submit proposals for experiments at ELBE. For the period January - June 2012 the deadline will be November 14th, 2011. Access is free of charge for all non- proprietary research. Proposals are evaluated by the scientific advisory committee of ELBE. Based on their recommendations the final decision and allocation of beam time will be made by an local panel headed by the Scientific Director of the HZDR.
The IR light from the two FELs is transported to several laboratories in the same building and to the adjacent building (through a 27 m long tunnel) of the High Magnetic Field Laboratory (HLD) as well, where the experimental setups are up to 70 m away from the FELs. Here, self-designed magnets for fields up to 90 T have successfully been tested and first experiments with IR beams have been carried out.
