Abstract
"Our consortium\footnote{ANR ""HEROES: HEterodyne Receivers OptimizEd for Synchrotron sources"", Grant number 16-CE30-0020-03} is currently developing a new spectrometer on the AILES beamline of the SOLEIL synchrotron facility to achieve sub-MHz resolution in the THz and far-IR regions. This spectrometer is based on heterodyne mixing of the far-IR synchrotron radiation with various local oscillators (LOs). In past years, we used a frequency multiplication chain to provide LO frequencies which enabled both a deep characterization of the spectral composition of the synchrotron emission\footnote{Tammaro, S., Pirali, O., Roy, P., Lampin, J.F., Ducournau, G., Cuisset, A., Hindle, F., Mouret, G. ""High density terahertz frequency comb produced by coherent synchrotron radiation"" Nature Communications, 6, 7733 (2015)} and the recording of its first Doppler limited absorption lines (of D$_2$O)\footnote{talk WI02, ISMS 2018}. We recently improved our set-up and measured absorption lines using a far-IR molecular laser pumped by a 10 $\mu$m QCL as the LO. The principle of the spectrometer, together with the first experimental results, will be presented in the talk."
