China Spallation Neutron Source Accelerators: Design, Research, and Development

摘要

The China Spallation Neutron Source (CSNS) is a newly approved high-power accelerator project based on a H(sup -) linear accelerator and a rapid cycling synchrotron. During the past year, several major revisions were made on the design including the type of the front end, the linac frequency, the transport layout, the ring lattice, and the type of ring components. Here, we discuss the rationale of design revisions, status of the R&D efforts, and upgrade considerations.
