Modeling the frequency response of microwave radiometers with QUCS
Andrea Zonca, Bastien Roucaries, Brian Williams +8
Characterization of the frequency response of coherent radiometric receivers is a key element in estimating the flux of astrophysical emissions, since the measured signal depends o…
Planck-LFI: Design and Performance of the 4 Kelvin Reference Load Unit
Luca Valenziano, Francesco Cuttaia, Adriano De Rosa +35
The LFI radiometers use a pseudo-correlation design where the signal from the sky is continuously compared with a stable reference signal, provided by a cryogenic reference load sy…
Optimization of Planck/LFI on--board data handling
M. Maris, M. Tomasi, S. Galeotta +34
To asses stability against 1/f noise, the Low Frequency Instrument (LFI) onboard the Planck mission will acquire data at a rate much higher than the data rate allowed by its teleme…
The Planck/LFI Radiometer Electronics Box Assembly
J. M. Herreros, M. F. Gomez, R. Rebolo +12
The Radiometer Electronics Box Assembly (REBA) is the control and data processing on board computer of the Low Frequency Instrument (LFI) of the Planck mission (ESA). The REBA was…
Thermal susceptibility of the Planck-LFI receivers
L Terenzi, M J Salmon, A Colin +33
This paper is part of the Prelaunch status LFI papers published on JINST: http://www.iop.org/EJ/journal/-page=extra.proc5/jinst . This paper describes the impact of the Planck Low…
Dynamic validation of the Planck/LFI thermal model
M. Tomasi, B. Cappellini, A. Gregorio +12
The Low Frequency Instrument (LFI) is an array of cryogenically cooled radiometers on board the Planck satellite, designed to measure the temperature and polarization anisotropies…
