Fast data acquisition with the CDF event builder

The CDF (Collider Detector at Fermilab) event builder is an intelligent FASTBUS device that performs parallel readout of a set of FASTBUS slaves on multiple-cable segments, formats the data, and writes the reformatted data to a FASTBUS slave module. The authors review the properties of this device and summarize its performance in the CDF data acquisition system. Preliminary performance of the prototype is being evaluated, and an event rate of approximately 30 Hz appears possible in the near future.<
