The CEBAF accelerator at Thomas Jefferson National Accelerator Facility (Jefferson Lab) successfully began its experimental nuclear physics program in November of 1995 and has since surpassed predicted machine availability. Part of this success can be attributed to using the EPICS (Experimental Physics and Industrial Control System) control system toolkit. The CEBAF control system is one of the...

An electron gun for a high-power electron linac in the Japan nuclear cycle development institute (JNC) has been developed and tested. In this electron gun, two types of grid control systems (mesh grid type and double aperture grid type) were tested for their ability to deliver high average current beams. In this paper, we discuss the problems associated with each type of gun system.

The distributed control system for the PSI accelerators provides optimized input output functions for closed loop control. These basic functions are then used to build generic applications for global online beam control. Some of these applications, including the basic mechanism used, are explained. Questions about testing and the quality of these closed loop controls are discussed. Resulting pe...

A relational database system Oracle was installed in the KEKB accelerator control system. The database contains all the data concerning accelerator components such as magnets, power supplies, vacuum ducts, pumps, control modules and so on. It keeps the history of the equipment, parameters of the component, physical location, electrical characteristics, wire connection list and so on. It is also...

Beam Commissioning for the damping ring of the KEK accelerator test facility (ATF) has been started since January 1997. Control system of the ATF accelerator i s based on the CAMAC-enhanced byte-serial highways handled by the Open-VMS Cluster system. Control software is integrated by using a commercial database application for process control. In this paper we present the status of the ATF cont...

This article presents the design and implementation of a software component for automated monitoring and diagnostic information analysis of a particle accelerator and its control system. The information that is analyzed can be seen as streams of events. A Complex Event Processing (CEP) approach to event processing was selected. The main advantage of this approach is the ability to continuously ...
