The new DAQ system for WASA at COSY

WASA (wide angle shower apparatus), a detector for charged and neutral particles, which is currently operated at the CELSIUS storage ring by TSL, Uppsala University, shall be transferred to the cooler synchrotron COSY at Forschungszentrum Julich (FZJ) after the anticipated shutdown of CELSIUS in summer 2005. For operation in Julich a new DAQ system is being developed, which conforms to the third generation of DAQ at COSY. This comprises of new readout electronics based on an optimized parallel bus with LVDS technology and FPGA-controlled event and buffer management, a synchronization system and a high speed optical link to the readout computer. Architecture of the new DAQ system and the technical issues of subsystems are presented
