Issue Date: | 2016 | Volume: | Ground-based and Airborne Telescopes VI | Editors: | Hall, Helen J.; Gilmozzi, Roberto; Marshall, Heather K. | Series: | PROCEEDINGS OF SPIE | Number: | 9906 | First Page: | 990645 | Abstract: | The Cherenkov Imaging Telescope Integrated Read Out Chip, CITIROC, is the front-end chip of the camera for the ASTRI SST-2M, one of the prototypes for the small sized telescopes of the Cherenkov Telescope Array, CTA. The telescope, operating in the energy range from a few TeV to beyond 300 TeV, is characterized by innovative technological solutions. The optical system is arranged in a dual-mirror configuration and the focal plane camera consists of a matrix of multi-pixel Silicon Photo-Multipliers. Among others, one of the most important project issue consists in the thermal characterization of the camera that, in the ASTRI SST-2M prototype, is thermo-controlled in a narrow temperature range. A set of at least nine similar telescopes will form the ASTRI mini-array proposed to be installed at the CTA southern site. In the cameras of the ASTRI mini-array telescopes the thermal control could be relaxed with a considerable gain in terms of power consumption, cost and simplicity. So, a study of the temperature dependence of the camera components is needed. The present work addresses this issue showing the results of the measurements carried out on CITIROC as a function of the temperature. We focused our investigation on the pedestal stability, linearity of the charge output signal, preamplifier gain and trigger uniformity in the temperature range 15-30°C. Our results show, for each of the above-mentioned measurable quantities, that temperature dependency is at the level of a few percent. | Conference Name: | Ground-based and Airborne Telescopes VI | Conference Place: | Edinburgh, UK | Conference Date: | 26 June-1 July, 2016 | URI: | http://hdl.handle.net/20.500.12386/24898 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9906/1/Temperature-characterization-of-the-CITIROC-front-end-chip-of-the/10.1117/12.2231099.short?SSO=1 | ISSN: | 0277-786X | ISBN: | 9781510601918 | DOI: | 10.1117/12.2231099 | Bibcode ADS: | 2016SPIE.9906E..45I | Fulltext: | open |
