Abstract

The LEPS2 data acquisition system (DAQ) is built on the network-distributed DAQ-middleware framework. It consists of gatherers that collect data from detector sub-systems, mergers that integrate data from gatherers, an event builder and a logger that writes data to files in the data acquisition software. The 10K TPC pad signals are transmitted to 16-channel FADC boards and transferred through the SpaceWire protocol to DAQ software components. We need to handle different subsystems with extensive variation in the number of channels. We have successfully commissioned the DAQ system of the LEPS2 detector, which includes a time projection chamber (TPC), drift chambers, resistive plate chambers, Pb/scintillator sampling calorimeters, and neutron counters. The LEPS2 DAQ system reads approximately 10K channels from TPC and 5K channels from other detector components at a trigger rate of 100-200 Hz and an event size of 40 MB/s.
