Data pubblicazione: | 2018 | Rivista: | JOURNAL OF INSTRUMENTATION | Numero: | 13 | Fascicolo: | 9 | Da pagina:: | P09011 | Abstract: | Multi-pixel fast silicon detectors represent the enabling technology for the next generation of space-borne experiments devoted to high-resolution spectral-timing studies of low-flux compact cosmic sources. Several imaging detectors based on frame-integration have been developed as focal plane devices for X-ray space-borne missions but, when coupled to large-area concentrator X-ray optics, these detectors are affected by strong pile-up and dead-time effects, thus limiting the time and energy resolution as well as the overall system sensitivity. The current technological gap in the capability to realize pixelated silicon detectors for soft X-rays with fast, photon-by-photon response and nearly Fano-limited energy resolution therefore translates into the unavailability of sparse read-out sensors suitable for high throughput X-ray astronomy applications. In the framework of the ReDSoX Italian collaboration, we developed a new, sparse read-out, pixelated silicon drift detector which operates in the energy range 0.5-15 keV with nearly Fano-limited energy resolution (<=150 eV FWHM @ 6 keV) at room temperature or with moderate cooling (~0°C to +20°C). In this paper, we present the design and the laboratory characterization of the first 16-pixel (4 × 4) drift detector prototype (PixDD), read-out by individual ultra low-noise charge sensitive preamplifiers (SIRIO) and we discuss the future PixDD prototype developments. | URI: | http://hdl.handle.net/20.500.12386/29527 | URL: | https://iopscience.iop.org/article/10.1088/1748-0221/13/09/P09011 | ISSN: | 1748-0221 | DOI: | 10.1088/1748-0221/13/09/P09011 | Bibcode ADS: | 2018JInst..13P9011E | Fulltext: | open |
