3 IL Progetto ASTRI The Project ASTRI has the main objectives to: _ Validate the Swarzschild Couder Optical Design (Never realized in a Cherenkov Telescope configuration) - Validate the ASTRI Camera design based on a novel technology of Sisicon Photon Detector. The Project ASTRI has the Goal to become the seed of the CTA SST configuration Nome Autore, con Luogo e 3 3

8 ASTRI Project wants to be the CTA seed so it has to compete on an international table. The major players are England, Germany, France, Swiss. On these tables the scientific excellence is not enough if Italy would like to be at the tiller among many other things. System Engineering Methodology are needed Nome Autore, con Luogo e 8 8

14 VCD: Preparation Planning: A ogni specifica viene dato un codice unico A ogni specifica viene identificato uno «shall Statement» Ogni specifica deve essere tracciato da almeno un requisito. Se non si trova nessun requisito la specifica è inutile. Si identifica un metodo di verifica e un momento nella pianificazione dove eseguire la verifica Il VCD viene rilasciato nella sua prima versione Nome Autore, con Luogo e 14 14

15 VCD: Preparation Esecuzione: Quando la specifica viene verificata si crea un report e si riporta il titolo in tabella Nel caso ci siano problemi essi sono indicati Nel caso si identifichi un problema che non può essere risolto si attiva un processo di RFW o RFD. Il VCD viene rilasciato in versioni successive quando serve. Nome Autore, con Luogo e 15 15

16 Some statistic ASTRI System VDC comprises of 350 lines for System and Subsystem specifications. 53% of such specifications will be verified by test The remaining specs will be verified by Analysis, Certification and Inspection. This is the right level of details requested by the CTA organization. ASTRI VCD will be translated in CTA Italy VCD (35 Telescopes). Configuration of NCR/RFD will gain importance.

17 Conclusion System Engineering is mandatory for modern international astrophysical projects. Configured System Engineering is not (yet) a common practice in such projects, but projects are increasing in complexity, dimension. The ASTRI VCD is a good compromise to MIUR requirements, CTA needs, best practices and efficient implementation in real life projects (i.e. considering ASTRI resources) Planning is (finally) ready, for the execution results see you next year.
