Free-Electron Lasers at the ELBE radiation source at the HZDR in Dresden-Rossendorf
FELBE is an acronym for the free-electron laser (FEL) at the Electron Linear accelerator with high Brilliance and Low Emittance (ELBE) located at the Forschungszentrum Dresden-Rossendorf, Germany. The heart of ELBE is a superconducting linear accelerator operating in cw mode with a pulse repetition rate of 13 MHz. The acceleration is performed in two superconducting units with 20 MV each. The average beam current is 1 mA. The electron beam is guided to several laboratories where secondary beams (particle and electromagnetic) are generated (→ details). Two free-electron lasers (U27-FEL and U100-FEL), produce coherent electromagnetic radiation in the mid and far infrared (4 - 250 µm). Pulse energies are in the few 100 nJ range with pulse duration of a few picoseconds. The typical operation mode offers 13 MHz micropulse repetition rate, in macropulses of a few 100 μs at up to 25 Hz or, alternatively, FEL operation in a continuous 13 MHz mode.
Applications for FEL beamtime are welcome!Next deadline: April 29th, 2013

The two free-electron lasers U27-FEL and U100-FEL with the undulators, U27 and U100, produce intense, coherent infrared radiation, which is tunable over a wide wavelength range by changing the electron energy or the undulator magnetic field.

The main parameters of the radiation produced by FELBE are as follows:
FELBE was a member facility in the Integrated Infrastructure Initiative (I3) project "European Light Sources Activities - Synchrotrons and Free Electron Lasers" (ELISA) within the 7th framework programme of the EU.and is presently involved in the initiative "wayforlight" for the implementation of a common access platform to all European synchrotons and FELs.
Here is more information aboutdiagnostic station first and then delivered to six user laboratories. In some of the labs there are table-top femtosecond lasers, which are synchronized to the FEL pulses, thus providing the possibility of multi-color pump-probe experiments.

Since 2007 the FELs are connected with the pulsed high-magnetic field laboratory.
