Development, Integration, and Implementation of the CDF Run II Data Acquisition System
Fermi National Accelerator Laboratory
The CDF experiment at the Tevatron is undergoing an extensive set of
upgrades to its abilities. During the coming collider run, CDF is
expected to trigger and record events from ppbar collisions corresponding
to instantaneous luminosities of ~10^32 cm-2 sec-1 with primary
collisions occuring every 132 nsec and typical event sizes of ~200Kbytes.
The implementation of a data acquisition system capable of efficiently
recording this data is the most critical element of the experimental design.
A presentation of the system pertaining to its developmental, integration, and
commisioning stages is made. Details are discussed with regards to the
structure of the software used in a system with widely dispersed processing
nodes, messaging technologies, and designs for monitoring of the system
