RHIC vacuum instrumentation and control system

Abstract

The Relativistic Heavy Ion Collider (RHIC) Project is a nuclear physics research accelerator at Brookhaven National Laboratory (BNL) with beam circulation scheduled for May 1999. To achieve the necessary beam lifetime, the vacuum in the two concentric rings must be constantly monitored to isolate problem vacuum regions. One function of the RHIC vacuum instrumentation and control (I&C) system is to operate sector valves with inputs from several hundred gauges and pumps distributed around the 3.8 km circumference of the accelerator rings. The architecture and implementation of the RHIC vacuum I&C system from the pumps and gauges to the remote user interfaces are described.

Design and development of the SNS ring vacuum instrumentation and control systems

“…The design of the instrumentation and control system for the SNS accumulator ring vacuum system was based on the architecture for the RHIC vacuum system [2,3], a versatile system, operational for over five years, with a few device model replacements to comply with SNS standards. The control system software is currently being developed on the SNS ring vacuum test stand shown in Figure 1.…”
