Space-Charge Simulations for the Spallation Neutron Source (SNS) Ring Using Unified Accelerator Libraries
- Brookhaven National Laboratory (BNL), Upton, NY (United States)
Although the tune depression in the ring is very small compared with high intensity linacs, space-charge contributions to beam loss through halo formation may be significant. The goal of achieving low-level beam loss becomes especially challenging in the presence of both the space charge and magnet imperfections. This puts very high expectations on the code used for computer simulations. The Spallation Neutron Source (SNS) ring dynamics presents a complex combination of several physical effects and dynamic processes. Some of them, such as field errors and misalignments are supported in general-purpose accelerator codes. Other ffects, such as space charge, are actual only for high intensity hadron rings and distributed into a set of independent specialized programs. A new SNS package, based on Unified Accelerator Libraries (UAL) environment, addresses all these effects together. This paper describes some basic features of the SNS simulation environment and demonstrates its application for the space-charge simulations in the SNS accumulator ring.
