THE SSCL PROCESS-CONTROL SYSTEM

The Superconducting Super Collider's (SSC) Process Control System was designed to account for 40% of the total I/O control points of the accelerator. It would have controlled the processes associated with the cryogenic refrigerators, vacuum systems, low conductivity water systems and instrument air system of the SSC. Although large scale, the technologies required to control and program such systems in an integrated manner is becoming available through industrial distributed systems controls vendors. This paper describes the proposed architecture of the SSCL Process Control System, how it is differentiated from the SSC Beam Controls and the techniques that would have been employed to integrate it into the SSCL Global Accelerator Control System.
