ASTRI is a flagship project of the Italian Ministry of Education, University and Research, which aims to develop an endto-
end prototype of one of the three types of telescopes to be part of the Cherenkov Telescope Array (CTA), an
observatory which will be the main representative of the next generation of Imaging Atmospheric Cherenkov
Telescopes.
The ASTRI project, led by the Italian National Institute of Astrophysics (INAF), has proposed an original design for the
Small Size Telescope, which is aimed to explore the uppermost end of the Very High Energy domain up to about few
hundreds of TeV with unprecedented sensitivity, angular resolution and imaging quality. It is characterized by
challenging and innovative technological solutions which will be adopted for the first time in a Cherenkov telescope: a
dual-mirror Schwarzschild-Couder configuration, a modular, light and compact camera based on silicon
photomultipliers, and a front-end electronic based on a specifically designed ASIC. The end-to-end project is also
including all the data-analysis software and the data archive.
In this paper we describe the process followed to derive the ASTRI specifications from the CTA general requirements, a
process which had to take into proper account the impact on the telescope design of the different types of the CTA
requirements (performance, environment, reliability-availability-maintenance, etc.). We also describe the strategy
adopted to perform the specification verification, which will be based on different methods (inspection, analysis,
certification, and test) in order to demonstrate the telescope compliance with the CTA requirements. Finally we describe
the integration planning of the prototype assemblies (structure, mirrors, camera, control software, auxiliary items) and
the test planning of the end-to-end telescope.
The approach followed by the ASTRI project is to have all the information needed to report the verification process
along all project stages in a single layer. From this unique layer it is possible to, in a semi-automatic way, generate
updated project documentation and progress report.
