Data acquisition systems at Fermilab

Experiments at Fermilab require an ongoing program of development for high speed, distributed data acquisition systems. The physics program at the lab has recently started the operation of a Fixed Target run in which experime nts are running the DART[1] data acquisition system. The CDF and D empty se t experiments are preparing for the start of the next Collider run in mid 2 000. Each will read out on the order of 1 million detector channels. In par allel, future experiments such as BTeV R&D and Mines have already started p rototype and test beam work. BTeV in particular has challenging data acquis ition system requirements with an input rate of 1500 Gbytes/sec into Level 1 buffers and a logging rate of 200 Mbytes/sec. This paper will present a general overview of these data acquisition system s on three fronts - those currently in use, those to be deployed for the Co llider Run in 2000, and those proposed for future experiments. It will prim arily focus on the CDF and DB architectures and tools.
