... short answer(s): EPICS: Experimental Physics and Industrial Control System
... a bit more elaborate: 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. (From the EPICS Home Page)
... striking: ... is three things at once:
an architecture for building scalable control systems
a collection of code and documentation comprising a software toolkit
a collaboration of major scientific laboratories and industriy
The center of gravity of EPICS is at APS, the Advanced Photon Source of the Argonne National Lab.
The EPICS Home Page at APS builds the home of EPICS, while it is not exclusively developed there, mind the collaborative character of EPICS.
