IRIS THz/Infrared Dipole Beamline
At synchrotron light sources of the second and third generation the emitted radiation in the infrared wavelength region is some orders of magnitude brighter than standard thermal broadband sources (e.g., globar). Infrared synchrotron radiation is an absolute source being polarized and pulsed in the picosecond timescale. As a particular speciality, BESSY II offers a new technique to generate high power, stabile and low-noise Coherent Terahertz (THz) Radiation.
The IRIS Beamline at BESSY was inaugurated in December 2001. The large acceptance beamline offering broadband infrared radiation from the THz to the NIR is equipped with several end-stations: e.g., a Fourier-transform infrared (FT-IR) spectrometer (Bruker 66/v), an infrared microscope (Thermo Nicolet Continuµm NexusTM) and a mid infrared mapping ellipsometer (developed at ISAS Berlin). In addition, a free beam port is applicable for breadboarding experiments.
