The LSPE (Large Scale Polarization Explorer ) is a balloon-borne mission aimed at measuring the polarization of the Cosmic Microwave Background (CMB) at large angular scales. High sensitivity will be achieved thanks to the use of new-concept mosaics of detectors and to the fact that the payload will fly in a circumpolar long duration balloon…

Feeds are the first passive components of the front end of radio receivers used to join the receiver with the parabolic reflector antenna. In radio astronomy, round shaped internally corrugated feeds are mainly used in order to guarantee top performances. In pictures (img. 1-6-7-8-9) there is a set of 7 out of 19 round corrugated…
