Abstract :
The main detector components of the Crystal Barrel (CBAR) experiment at the Low Energy Antiproton Ring (LEAR) at CERN are two proportional wire chambers, a jet drift chamber and an electromagnetic calorimeter composed of 1380 CsI(Tl) crystals, with a total of 4380 analog channels. A description is given of the use of distributed VME-based microcomputers to collect data from the various subdetectors and to merge the full event information in a global event builder. At this level the data are transferred to a μVAX for tape storage and monitoring
