Abstract: The SAGACE experiment consists of a mm-sub-mm telescope with a 3-m diameterprimary mirror, coupled to a cryogenic multi-beam differential spectrometer.SAGACE explores the sky in the 100-760 GHz frequency range, using fourdiffraction-limited bolometer arrays. The instrument is designed to performspectroscopic surveys of the Sunyaev-Zeldovich effects of thousands of galaxyclusters, of the spectral energy distribution of active galactic nuclei, and ofthe CII line of a thousand galaxies in the redshift desert. In 2008 a fullphase-A study for a national small mission was completed and delivered to theItalian Space Agency ASI. We have shown that taking advantage of thedifferential operation of the Fourier Transform Spectrometer, this ambitiousinstrument can operate from a Molniya orbit, and can be built and operatedwithin the tight budget of a small mission.
