Update On The Triumf Central Control System

Abstract

The continuing evolution of the TRIUMF Central Control System is currently subject to three major influences. Most imperative is the need to replace the obsolete Nova computers that still handle much of the routine cyclotron operation. Smooth integration of a number of isolated control systems into the CCS is another focus. The third major force arises from the requirements of developing new projects in a system that has reached serious expansion constraints. The plan for phasing out the Novas, integrating the orphaned systems and allowing expansion of the CCS in a smooth fashion is discussed. This is a conservative approach, relying on the strengths of the present hardware configuration, the substantial financial investment in existing equipment, and the expertise of available personnel, while meeting the present and future requirements. Details of the modified and expanded hardware configuration are described. This review also briefly mentions new support for device access, X-window ..
