Title: | Effect of Sorption Cooler temperature variations on LFI front-end | Authors: | MENNELLA, ANIELLO Bersanelli, Marco Ferretti, Roberto MORGANTE, GIANLUCA Prina, Mauro BURIGANA, CARLO Maino, Davide |
Issue Date: | 2001 | Number: | PL-LFI-PST-TN-005 | Abstract: | In this technical note we provide a major update of the analysis of impact of front-end thermal fluctuation on LFI measurements. In this update we consider JPL latest simulations concerning the stability of the Sorption Cooler Cold End, the thermal damping provided by the LFI mechanical structure and the partial removal of the final systematic effect from the LFI maps obtained using a so-called “destriping” algorithm. Our results indicate that although several factors contribute to reduce the impact of Sorption Cooler thermal instabilities on the measured sky signal, the final systematic effect cannot be considered negligible, especially if the Sorption Cooler will not work under ideal conditions. | URI: | http://hdl.handle.net/20.500.12386/34876 | Fulltext: | open |
