O172400100012 DETECTOR (TELES,SIBAR,NAICR) The proton telescopes consists O172400100013 of a 1 mm silicon surface barrier transmission O172400100014 detector followed by a 7.6 cm diameter by 5.1 cm thick O172400100015 NaI(Tl) crystal- phototube assembly. O172400100016 The alpha-particle telescopes consists of a 100 mum O172400100017 silicon surface barrier transmission detector followed O172400100018 by two 2 mm Si surface-barrier transmission detectors, O172400100019 which were then followed by a 7.6 cm diameter by 5.1 cmO172400100020 thick NaI(Tl) crystal- phototube assembly which acted O172400100021 as veto for energetic protons.
