Description

The China Spallation Neutron Source (CSNS) is a large multidisciplinary experimental facility that generates neutrons by targeting a strong current proton accelerator. Its linear accelerator consists of a front-end accelerator, a 3 MeV RFQ accelerator, and an 80 MeV DTL accelerator. The second phase of the project will upgrade the linear accelerator by installing superconducting cavities after the DTL exit, increasing the beam energy to 300 MeV. This paper will present a simulation study that examines the effects of different magnets and cavity failures in the linear accelerator on beam quality, including emittance growth and beam loss.
