LSPE is a novel project that combines ground-based (STRIP) and balloon-borne (SWIPE) polarization measurements of the microwave sky on large angular scales to attempt a detection of the \"B-modes\" of the Cosmic Microwave Background polarization. STRIP will observe approximately 25% of the Northern sky from the \"Observatorio del Teide\" in Tenerife, using an array of forty-nine coherent polarimeters at 43 GHz, coupled to a 1.5 m fully rotating crossed-Dragone tele","authors_text":"A.
