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

摘要

BNL is undertaking the design, construction and commissioning of the SpallationNeutron Source (SNS) accumulator ring and the beam transport lines (l). Ultrahigh vacuum of 10(sup (minus)9) Torr is required in the accumulator ring to minimize beam-gas ionization, a contributing factor to the e-p instability observed in a few high-intensity proton storage rings. All vacuum instrumentation must be capable of local and remote operation to achieve a reliable vacuum system, especially in this extremely high intensity accelerator. The design and development of the SNS ring vacuum instrumentation and control through the Experimental Physics and Industrial Control System (EPICS) distributed real-time software tools are presented.
