Data pubblicazione: | 2018 | Rivista: | JOURNAL OF LOW TEMPERATURE PHYSICS | Numero: | 193 | Fascicolo: | 5-6 | Da pagina:: | 793 | Abstract: | The X-ray Integral Field Unit (X-IFU) is one of the two instruments of the Athena astrophysics space mission approved by ESA in the Cosmic Vision Science Program. The X-IFU consists of a large array of TES microcalorimeters that will operate at 50 mK inside a sophisticated cryostat. A set of thin filters, highly transparent to X-rays, will be mounted on the cryostat thermal shields in order to attenuate the IR radiative load, to attenuate RF electromagnetic interferences, and to protect the detector from contamination. In this paper, we present the current thermal filters design, describe the filter samples developed/procured so far, and present preliminary results from the ongoing characterization tests. <P /> | URI: | http://hdl.handle.net/20.500.12386/34781 | ISSN: | 0022-2291 | DOI: | 10.1007/s10909-018-1942-z | Bibcode ADS: | 2018JLTP..193..793B | Fulltext: | open |
