This paper discusses the present data acquisition system (DAQ) of the COMPASS experiment at CERN and presents development of a new DAQ. The new DAQ must preserve present data format and be able to communicate with FPGA cards. Parts of the new DAQ are based on state machines and they are implemented in C++ with usage of the QT framework, the DIM library, and(More)
This paper describes the route of events through both hardware and software parts of the data acquisition system (DAQ) of the COMPASS experiment at CERN which implements FPGA based event-building. Data quality control is important part of any DAQ. During development of the COMPASS DAQ, a great emphasis was put on ability to recover from errors coming from(More)
