The Advanced Photon Source uses two distinct control programs for orbit control and stability—a full-featured workstation-based program for orbit control (sddscontrollaw) and an EPICS-based system, the RealTime Fast Feedback System (RTFS), to reduce orbit motion. The sddscontrollaw program has been ported to EPICS and moved from the UNIX environment to an EPICS IOC attached to the RTFS. This EP...

The control system for Pohang Light Source (PLS) was designed about twelve years ago and has been working without serious problem so far. However, as the demand for the application programs for accelerator physics and data analysis increases, the present control system shows the lack of flexibility and control speed. To have faster and more flexible performance, we have decided to convert the c...

One of the open source software tool kit is EPICS (Experimental Physics and Industrial Control System) developed and maintained by Argonne National laboratory, US and is in use worldwide. It maintains the server client distributed control system. Communication between server and client are done through a named piece of data called Process Variable (PV). There may be many client and many servers...

The Duke Free Electron Laser Laboratory currently operates two FELs: the OK-4/Duke Storage Ring FEL, and the Mark III IR FEL. Both of these systems were among the early adopters of the Experimental Physics and Industrial Control System (EPICS). The Mark III EPICS control system was completed and operational in September, 1993. The Duke Storage Ring was commissioned in November of 1994 using EPI...

The communications protocols utilized in the Experimental Physics and Industrial Control System (EPICS) have been in use, essentially unchanged, for more than 10 years. With more than 100 EPICS sites worldwide, there is increasing justification for performance and functional upgrades, but with a paramount requirement to remain backward compatible with the existing user base. The future viabilit...

The only proof of this I know is kind of fiddly and not enlightening. But the point is that in most categories that appear ‘in nature,’ regular, strong, and extremal epics are about the same, and all are the correct notion of quotient, while ordinary epimorphisms may not be. For example, N→ Q is epic in Rings, but not extremal epic. In Top the epics are the surjective maps, while the regular = ...

The Experimental Physics and Industrial Control System (EPICS) requires expensive hardware and software to provide the high performance and high reliability required for accelerator control. No more than several years ago, personal computers based on Intel x86 microprocessors lacked computing power to compete with workstations, such as SPARCstation. However, with the advent of the high performa...

This article describes concepts and mechanisms used in porting of EPICS (Experimental Physical and Industrial Control System) codes to platform of operating system UNIX. Without destruction of EPICS architecture, new features of EPICS provides the support for real time operating system LynxOS/x86 and equipment produced by INP (Budker Institute of Nuclear Physics). Application of ported EPICS re...

A control system for Hall B at the Thomas Jefferson National Accelerator Facility is being developed within the framework of the Experimental Physics and Industrial Control System (EPICS). The Hall B equipment currently under EPICS control includes numerous beam line devices, high voltage power supplies, detector gas systems, and safety systems. The status of the control system is described.

This study explores the impact of the Effective Practices in Community Supervision (EPICS) model on offender perceptions of their collaborative working relationships with supervising probation or parole officers. The data in this study was collected as part of an EPICS project at the University of Cincinnati. The results examine the nature and quality of offender perceptions of their probation ...
