  "description": "<p>This paper deals with the processes involved in the generation of reliable experimental<br>\ndata for the validation of computer simulations. In the field of neutron noise, the analysis<br>\nof results is based on spectral features of the detector signals in the frequency domain.<br>\nNeutron noise simulators also produce estimates that are subjected to studies in the same<br>\ndomain. The validation process of such simulations begins with the generation of reliable<br>\nexperimental data. In this work, we analyze results from two neutron noise experimental<br>\ncampaigns. The focus is placed upon de comparison of results obtained by different data<br>\nacquisition systems (DAQs) that were used to record the data in parallel. The goal is to<br>\nverify whether results obtained by the different DAQs are consistent, and thus reliable.<br>\nThe neutron noise-dedicated experiments were carried out in the AKR-2 reactor at the<br>\nTechnische Universit&auml;t Dresden and in the CROCUS reactor at the &Eacute;cole polytechnique<br>\nf&eacute;d&eacute;rale de Lausanne. The experiments consisted in introducing different types of periodic<br>\nreactivity perturbations: a rotating neutron absorber with a varying absorption crosssection<br>\nwith respect to the rotation angle; a linearly vibrating absorber that is moved back<br>\nand forth inside the reactor core; and a fuel rods oscillator that allows to vibrate a set of<br>\nfuel rods.</p>",
