EPICS - Experimental Physics and Industrial Control System

Experimental Physics and Industrial Control System

EPICS Home at Argonne

EPICS is a set of Open Source software tools, libraries and applications developed collaboratively and used worldwide to create distributed soft real-time control systems for scientific instruments such as a particle accelerators, telescopes and other large scientific experiments.

The EPICS-Controls website is a community-run site which is slowly taking over as the primary home page for the EPICS Collaboration. This site will continue to exist at APS (and will provide the mailing list archives for the forseeable future) but it may transition to hosting more specialized and Argonne-specific materials.

The best place to start looking for documentation about EPICS is now the EPICS Documentation website, although for some specific information it will point to external web-servers provided by the projects that maintain the software.
