The Cologne laboratory astrophysics group lead by Prof.Schlemmer harbours one of the best equipped high-resolution spectroscopy laboratories. The infrastructure comprises several THz absorption spectrometers in the frequency range 0.1 – 2 THz, two chirped pulse Fourier transform spectrometers in the microwave and cm wavelength regimes, an infrared laser multi-path absorption spectrometer with a free jet source, and a set of custom-built ion-trap apparatus. The operation of these facilities as international user facilities has been DFG-funded via the Cologne Centre for THz Spectroscopy as a ‘DFG core facility’.
