Agencia Estatal de Investigación (AEI); Ministerio de Ciencia e Innovación (MICINN); Centre National D'Etudes Spatiales (CNES); Agenzia Spaziale Italiana (ASI); European Space Agency (ESA)The Athena X-ray Integral Unit (X-IFU) is the high resolution X-ray spectrometer, studied since 2015 for flying in the mid-30s on the Athena space X-ray Observatory, a versatile observatory designed to address the Hot and Energetic Universe science theme, selected in November 2013 by the Survey Science Committee. Based on a large format array of Transition Edge Sensors (TES), it aims to provide spatially resolved X-ray spectroscopy, with a spectral resolution of 2.5 eV (up to 7 keV) over an hexagonal field of view of 5 arc minutes (equivalent diameter). The X-IFU entered its System Requirement Review (SRR) in June 2022, at about the same time when ESA called for an overall X-IFU redesign (including the X-IFU cryostat and the cooling chain), due to an unanticipated cost overrun of Athena. In this paper, after illustrating the breakthrough capabilities of the X-IFU, we describe the instrument as presented at its SRR, browsing through all the subsystems and associated requirements. We then show the instrument budgets, with a particular emphasis on the anticipated budgets of some of its key performance parameters. Finally we briefly discuss on the ongoing key technology demonstration activities, the calibration and the activities foreseen in the X-IFU Instrument Science Center, and touch on communication and outreach activities, the consortium organisation, and finally on the life cycle assessment of X-IFU aiming at minimising the environmental footprint, associated with the development of the instrument. Thanks to the studies conducted so far on X-IFU, it is expected that along the design-to-cost exercise requested by ESA, the X-IFU will maintain flagship capabilities in spatially resolved high resolution X-ray spectroscopy, enabling most of the original X-IFU related scientific objectives of the Athena mission to be retained.Publicación Restringido Radiated Emission Measurements in Close Proximity to the Noise Floor(IEEE, 2025-05) Jiménez Lorenzo, María; Medler, JensRadiated Emission (RE) measurements in close proximity to the noise floor can lead to an overestimation of the measurement results, which may cause a failure situation when performing the limit check. This may be the case when this test is performed on an aerospace system because of the low electric field limits defined in certain frequency ranges to protect critical receiver bands and a high sensitivity of the measuring system is required. Standards define a requirement for the noise floor to be at least 6 dB below the applicable limit. This is not always feasible when measuring low limit frequency notches using the standard bandwidths and test setups. This paper focuses on the analysis of three different ways of decreasing the noise level and improving the sensitivity of the measuring system: the use of low noise preamplifiers, the use of high gain antennas and the narrowing of the measuring bandwidth.Publicación Restringido Medidas de Emisiones Radiadas de Alta Sensibilidad en Sistemas Espaciales(INSTITUTO TECNOLÓGICO DE ARAGÓN, 2025-11) Medler, Jens; Jiménez Lorenzo, MaríaDurante los ensayos de emisiones radiadas, la proximidad del nivel de ruido al límite aplicable tiene un impacto directo en los resultados. Este aspecto debe ser tenido en cuenta durante las medidas de emisiones radiadas en sistemas espaciales donde se definen límites muy restrictivos en determinadas bandas de frecuencia (conocidas como notches) para proteger los sistemas electrónicos sensibles como son los receptores. En esta presentación se describe la influencia del nivel de ruido en los resultados obtenidos y se evalúan diferentes métodos para mejorar la sensibilidad del sistema de medida y su posible efecto en el resultado final del ensayo.
