The Belle II experiment, a new generation B-factory experiment at KEK to search for new physics beyond the standard model, is scheduled to start in 2017. The maximum trigger rate is expected to reach as high as 20 kHz with the raw event size of more than 1 MB and we set the designed trigger rate to 30 kHz for the data acquisition (DAQ) system. This requirement for the data acquisition is a big challenge...
In the data acquisition (DAQ) system of the Belle II experiment, COmmon Pipeline Platforms for Electronics Readout (COPPER) boards developed at KEK are to be used for the unified interface with front-end detectors, except for an innermost pixel detector which needs a dedicated data reduction system. A COPPER board receives and processes the data from the front-end electronics via common optical links...
The Belle II experiment, a new generation B-factory experiment at KEK aiming to search for new physics beyond the standard model, is scheduled to start in 2016. The maximum trigger rate is expected to reach as high as 30 kHz with the raw event size of more than 1MB, and the data acquisition is a big challenge. The Belle II DAQ system is a synchronous system based on a pipelined trigger flow control...
