Hitherto data acquisition systems in laboratories were characterized by flexible setups, but slow data rates. High data rates are mainly realized in fixed setups at large accelerator experiments. This poster presents a solution, which involves both - high data rates and flexible usability.

The DAQ of the COMPASS-Experiment at CERN has been adapted for laboratory purpose with two additional modules - a trigger-logic-controller and a trigger-distributor - substituting the sophisticated trigger system. In our system trigger signals are generated by a programmable combinatoric logic in a VME-module using modern FPGA technology. Alternatively the module can be used as a programmable prescaler. The second module, realized in NIM-standard, provides a fan out for the trigger signals and the experiment clock. It interfaces to the existing DAQ, in particular to the Freiburg CATCH-module.

The DAQ system is scalable and conveniently adjustable to different inputs due to exchangeable mezzanine cards, what makes it interesting for a variety of experiments.
