Abstract

The main scientific object of the Planck ESA (European Space Agency) mission is the imaging of the anisotropies of the Cosmic Microwave Background (CMB) over the whole sky, with unprecedented sensitivity and angular resolution. This target will be achieved by the synergic performance of the two instruments onboard: the High Frequency Instrument (HFI) and the Low Frequency Instrument (LFI). The first is composed of 48 bolometers observing in six spectral bands from 100 GHz to 857 GHz; the latter is an array of 46 radiometers covering four microwave bands from 30 to 100 GHz. A description of the Low Frequency Instrument, together with its characteristics and performance, is reported in this paper.
