Abstract
In this technical note we provide a preliminary estimation of the impact of temperature fluctuations at the
level of different thermal stages on the output signal of the Planck-LFI radiometers. Thermal susceptibilties
at the level of Front End Modules (FEMs), Back End Modules (BEMs) and 4K Reference Loads have been
evaluated throughout the ground test phases of the instrument. Due to bias optimization and different
environmental conditions an in-flight measurement is needed to get an estimate of the temperature
fluctuations impact on science and to setup an attempt of reduction of such a systematic effect by using
houskeeping informations.
