CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishA 50 x 50 cm2 RICH detector was tested with hadron beams of 200 GeV/c to determine the resolution and efficiency of the system. Single photon detection has been achieved with a multistep avalanche chamber in conjunction with a CCD camera equipped with a 35 mm f/1.4 lens coupled to a two stage image intensifier. The results show that for the number of photons detected with the present setup and the geometry used in proximity focusing a standard deviation of 7.5 mrad per event has been achieved for the reconstruction of the Cherenkov angle.
