The X-IFU focal plane assembly development model: microvibrations characterization

17 June 2024 • 16:25 - 16:40 Japan Standard Time | Room G414/415, North - 4F

Abstract

This paper describes the micro-vibrational characterization of the Development Model (DM) of the X ray Integral Field Unit Focal Plane Assembly (X-IFU FPA) for the Athena X-ray observatory. We discuss the power dissipation occurring when FPA modes are excited. We compare amplitude and phase measured by X-Z accelerometers, thermometers response and the pixels DC baseline signal due to acceleration provided by actuator towards the FPA center of mass. Impact of the micro-vibrations on the thermal stability at the detectors level and the possible degradation on the pixels performance will be discussed in detail.

Emanuele Taralli is instrument scientist at Netherland Institute for Space Research (SRON) and his field of interest are single photon detectors, in particular transition-edge sensors TES microcalorimeters for X-ray detection. He is currently involved in the characterisation and development of the Focal plane assembly (FPA) of the X-ray Integral Field of Unit (X-IFU), one of the two instruments aboard of ATHENA space telescope.
