The OLIMPO experiment is a balloon borne 2.6 m telescope for cosmology observations at frequencies between 140 and 450 GHz. The experiment is aimed at precision measurement of the cosmic microwave background (CMB), and in particular at the measurement of the spectral distortion of the CMB in the direction of rich clusters of galaxies (Sunyaev-Zeldovich eect). In a single long duration flight OLIMPO will be able to measure the decrement and the increment of the CMB in more than 50 carefully selected clusters. Moreover, OLIMPO will measure the power spectrum of diuse sky radiation at multipoles up to ` 2500, simultaneously in four well intercalibrated frequency bands, allowing precise spectral tests of the measured anisotropy. OLIMPO can be considered a precursor for the satellite fully spectroscopic mission SAGACE, now a phase-A study of the Italian Space Agency. In this paper we describe the scientific programme of OLIMPO, the measurement method and the technical implementation.

Abstract
The OLIMPO experiment is a balloon borne 2.6 m telescope for cosmology observations at frequencies between 140 and 450 GHz. The experiment is aimed at precision measurement of the cosmic microwave background (CMB), and in particular at the measurement of the spectral distortion of the CMB in the direction of rich clusters of galaxies (Sunyaev-Zeldovich eect). In a single long duration flight OLIMPO will be able to measure the decrement and the increment of the CMB in more than 50 carefully selected clusters. Moreover, OLIMPO will measure the power spectrum of diuse sky radiation at multipoles up to ` 2500, simultaneously in four well intercalibrated frequency bands, allowing precise spectral tests of the measured anisotropy. OLIMPO can be considered a precursor for the satellite fully spectroscopic mission SAGACE, now a phase-A study of the Italian Space Agency. In this paper we describe the scientific programme of OLIMPO, the measurement method and the technical implementation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
