dc.description.abstract | In this technical note we present an evaluation of the effect of sorption cooler induced temperature fluctuations Planck-LFI using temperature data measured in flight. In particular we analyse three scenarios in order to evaluate the effect of TSA capability to damp temperature fluctuations at the sorption cooler cold end. The first scenario is one in which the TSA is completely off and the LFI is subject to the complete spectrum of the cold end temperature variations. The second scenario is one in which the TSA is working nominally and the third scenario is one in which the TSA is working in a not-nominal situation because of sorption cooler aging. The analysis, performed with two, independent methods, show clearly a negative impact of the increased level of temperature fluctuations on the LFI maps. In particular, estimates of the effect in case the TSA were kept off for a significant fraction of the sky coverage indicate that the effect would not be compatible with the LFI scientific requirements. | en_US |
