Title :
Spallation Neutron Source ring status, challenges, issues, and perspectives
Abstract :
The Spallation Neutron Source (SNS) ring is designed to accumulate beam pulses of 1.5 × 1014 protons of 1 GeV kinetic energy at a repetition rate of 60 Hz. At such beam intensity and power, key design challenges include control of beam loss and radio-activation, construction of high-quality large-aperture magnets and power supplies, design of robust injection and extraction systems, minimization of beam-coupling impedances, and mitigation of electron-cloud effects. This paper discusses the status of the ring systems with emphasis on technical challenges and issues, and presents future perspectives towards a next-generation high-intensity facility.
