We present a concept for the payload SAGACE, the Spectroscopic Active Galaxies And Cluster Explorer, devoted to study the evolution of Universe structures using different observables, all of them in the rmn/submm wavelength. The SAGACE payload is made of a passively cooled 3m telescope, a cryogenic Fourier Transform Spectrometer (FTS) and detector arrays to be operated at 0.3 K by a3He fridge. The detectors are Ti/Au Transition Edge Sensor (TES) bolometers with a NEP<1017W/Hz1/2. A phase-A study has been recently completed for this experiment, in the framework of the call for small missions of the Italian Space Agency. © 2009 American Institute of Physics.
