Planck pre-launch status: Design and description of the Low Frequency Instrument
M. Bersanelli, N. Mandolesi, R. C. Butler +109
In this paper we present the Low Frequency Instrument (LFI), designed and developed as part of the Planck space mission, the ESA program dedicated to precision imaging of the cosmi…
Noise Properties of the Planck-LFI Receivers
P. Meinhold, R. Leonardi, B. Aja +47
The Planck Low Frequency Instrument (LFI) radiometers have been tested extensively during several dedicated campaigns. The present paper reports the principal noise properties of t…
Planck early results. III. First assessment of the Low Frequency Instrument in-flight performance
A. Mennella, M. Bersanelli, R. C. Butler +158
The scientific performance of the Planck Low Frequency Instrument (LFI) after one year of in-orbit operation is presented. We describe the main optical parameters and discuss photo…
Planck pre-launch status: calibration of the Low Frequency Instrument flight model radiometers
F. Villa, L. Terenzi, M. Sandri +71
The Low Frequency Instrument (LFI) on-board the ESA Planck satellite carries eleven radiometer subsystems, called Radiometer Chain Assemblies (RCAs), each composed of a pair of pse…
Planck pre-launch status: Low Frequency Instrument calibration and expected scientific performance
A. Mennella, M. Bersanelli, R. C. Butler +83
We give the calibration and scientific performance parameters of the Planck Low Frequency Instrument (LFI) measured during the ground cryogenic test campaign. These parameters char…
Advanced pseudo-correlation radiometers for the Planck-LFI instrument
A. Mennella, M. Bersanelli, R. C. Butler +34
The LFI (Low Frequency Instrument) on board the ESA Planck satellite is constituted by an array of radiometric detectors actively cooled at 20 K in the 30-70 GHz frequency range in…
