SSAM (Submillimeter Spectrometer for Astrophysical Molecules)
We have developed a millimeter and submillimeter-wave spectrometer dedicated to the investigation of the rotational spectrum of both stable and reactive species of astrophysical interest. The spectrometer, based on the exploitation of electronic sources and a frequency multiplication chain (VDI), operates in the 75 - 900 GHz region thus matching ideally the current astronomical observations using for instance ALMA and NOEMA.
Several set-ups allowing the production of reactive species can be coupled with the SSAM spectrometer: radiofrequency, microwave, or electrical discharges cells, and reaction cell for abstraction of H atoms by atomic F.
