Data pubblicazione: | 2020 | Rivista: | JOURNAL OF LOW TEMPERATURE PHYSICS | Numero: | 199 | Fascicolo: | 1-2 | Da pagina:: | 65 | Abstract: | The Cryogenic AntiCoincidence detector (CryoAC) of ATHENA X-IFU is designed to reduce the particle background of the instrument and to enable the mission science goals. It is a 4-pixel silicon microcalorimeter sensed by an Ir/Au TES network. We have developed the CryoAC demonstration model, a prototype aimed to probe the critical technologies of the detector, i.e., the suspended absorber with an active area of 1 cm<SUP>2</SUP>; the low energy threshold of 20 keV; and the operation connected to a 50 mK thermal bath with a power dissipation less than 40 nW. Here, we report the test performed on the first CryoAC DM sample (namely, the AC-S10 prototype), showing that it is fully compliant with its requirements. | URI: | http://hdl.handle.net/20.500.12386/34976 | URL: | https://link.springer.com/article/10.1007/s10909-019-02300-9 | ISSN: | 0022-2291 | DOI: | 10.1007/s10909-019-02300-9 | Bibcode ADS: | 2020JLTP..199...65D | Fulltext: | open |
