8 Mar 2013 | | Abstract: | ASTRI ("Astrofisica con Specchi a Tecnologia Replicante Italiana") is a
flagship project of the Italian Ministry of Education, University and Research.
Within this framework, INAF is currently developing a wide field of view (9.6
degrees in diameter) end-to-end prototype of the CTA small-size telescope
(SST), devoted to the investigation of the energy range from a fraction of TeV
up to tens of TeVs, and scheduled to start data acquisition in 2014. For the
first time, a dual-mirror Schwarzschild-Couder optical design will be adopted
on a Cherenkov telescope, in order to obtain a compact optical configuration. A
second challenging, but innovative technical solution consists of a modular
focal surface camera based on Silicon photo-multipliers with a logical pixel
size of 6.2mm x 6.2mm. Here we describe the current status of the project, the
expected performance, and its possible evolution in terms of an SST mini-array.
This CTA-SST precursor, composed of a few SSTs and developed in collaboration
with CTA international partners, could not only peruse the technological
solutions adopted by ASTRI, but also address a few scientific test cases that
are discussed in detail. | | Source: | arXiv, 1303.2024 | | Services: | Forum | Review | PDF | Favorites | |
