Abstract

The main scientific goal for European Space Agency's Planck mission is to measure Cosmic Microwave Background (GMB) radiation anisotropy with a great angular resolution, the accuracy of which is only limited by the laws of astropbysics. In addition to the telescope, The Planck spacecraft will have two instruments on board: Low Frequency Instrument (LFI) and High Frequency Instrument (HFI). The LFI comprises receivers for 30, 44, 70 and 100 GHz frequencies. The HFI, for its part, has receives for frequencies of 100, 143, 217, 353, 545 and 857 GHz using bolometers.
