The spectral coverage at these temperatures ranges from the visible to less than 10 cm$^{-1}$, thanks to the use of diamond windows. The design of the cryostatic and vacuum set-up allows vibration-free operation. The equipment provides for temperature homogeneity and pressure control to better than 2 percent over the 100 to 400K and 0.1 to 1000 mbar ranges. Remote-controlled opto-mechanical systems enable in situ readjustements as well as changes of the optical path length within half an hour, in order to optimize measurement time in an open user facility. The design and performance of the equipment will be briefly presented and illustrated on spectroscopic examples. This new instrument opens up the way for many experiments in the field of high-resolution gas-phase IR spectroscopy, in particular in quantitative spectroscopy for atmospheric applications: measurements of absorption line parameters (absolute intensities and pressure-induced widths) using Fourier transform spectroscopy. en_US dc.language.iso en en_US dc.publisher Ohio State University en_US dc.title A NEW, LOW TEMPERATURE LONG PATH CELL FOR MID-IR to THz SPECTROSCOPY WITH SYNCHROTRON RADIATION AT SOLEIL en_US dc.type Article en_US dc.type Image en_US dc.type Presentation en_US
