The LSPE/STRIP project |
Abstract |
We present here the status of the low frequency instrument (STRIP) of the Large Scale Polarization Explorer (LSPE). LSPE is a project that combines ground-based (STRIP) and balloon-borne (SWIPE) polarization measurements of the microwave sky on large angular scales, trying to detect the primordial ÒB-modesÓ of the Cosmic Microwave Background. STRIP will observe approximately 25% of the Northern sky from the Tenerife site in Canary Island, using an array of forty-nine cryogenic coherent polarimeters at 43 GHz, coupled to a 1.5 m telescope in crossed Dragone configuration. A second frequency channel with six-elements at 95 GHz will be exploited mainly as an atmospheric monitor. STRIP will be able to continuously spin around the azimuth azis at different elevations to reach the sky coverage and the celestial calibrators. The sensitivity of the two instruments, together with an efficient scanning strategy and an effective component separation, will allow us to constrain the tensor-to-scalar ratio to about 0.03. |
