BELLE DAQ SYSTEM


On 29-Oct-1997, we have successfully transferred the data from detector subsystems to the central recording system (The picture of data-route for display and for printer.). The system consists of two detector subsystems, switch-type event-builder, two sets of online-farm, Fujitsu optical transfer system and the central recording system. We tested 2x2 data transfer. Unfortunatelly, only one Fujitsu module was available at that time, only half of the data were transferred.
