National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Control Architecture of the DO Experiment.

Publication Date	2002

Abstract	From a controls viewpoint, contemporary high energy physics collider detectors are comparable in complexity to small to medium size accelerators: however, their controls requirements often differ significantly. DO, one of two collider experiments at Fermilab, has recently started a second, extended running period that will continue for the next five years. EPICS , an integrated set of software building blocks for implementing a distributed control system, has been adapted to satisfy the slow controls system, has been adapted to satisfy the slow controls needs of the DO detector by (1) extending the support for new device types and an additional field bus, (2) by the addition of a global event reporting system that augments the existing EPICS alarm support, and (3) by the addition of a centralized database with supporting tools for defining the configuration of the control system. This paper discusses the control architecture of the current DO experiment, how the EPICS system was 4extended to meet the control requirements of a large, high-energy physics detector, and how a formal control sys6tem contributes to the management of detector operations.
