The High Frequency Instrument

The High Frequency Instrument (HFI) is an array of 48 bolometric detectors which will be placed in the focal plane of the Planck telescope, and will image the sky in six frequency channels between 100 and 857 GHz. The HFI is being designed and built by a Consortium of scientists led by Jean-Loup Puget (PI) of the Institut d'Astrophysique Spatiale in Orsay (France), and Francois Bouchet (Deputy PI) of the Institut d'Astrophysique de Paris. The other main institutes involved in the HFI Consortium are:
