The Run II Data Acquisition (DAQ) system of the CDF Detector at
Fermilab's Tevatron accelerator has been operational since July 2001. CDF
DAQ has collected over 350 inverse picobarns of proton-antiproton collision
data with high efficiency. An overview of the design of the pipelined,
deadtimeless trigger and data acquisition system will be presented. CDF can
receive and process a maximum crossing rate of once per 132 ns, with the
rate reduced in three stages to the final output of approximately 1 to 2
terabytes per day. The DAQ system is controlled and monitored via a suite
of Java based control software, with connections to front end VME crate
processors running VxWorks/C and back end Oracle databases. Included are a
flexible and easy to use Run Control java application and associated system
monitoring applications, both stand-alone and web based. The performance
and operational experience of three years will be presented, including data
taking efficiencies and through-put, and the role of intelligent software in
tagging and solving problems. We also review future upgrades designed to
increase data collection rates to cope with increased Tevatron luminosity.
