Description

The China Spallation Neutron Source (CSNS) officially initiated its power upgrade project(CSNS-Ⅱ) in 2024, aiming to raise the accelerator beam power from 100kW to 500kW. The CSNS accelerator consists of an 80 MeV normal conducting linear accelerator and a 1.6 GeV rapid cycling synchrotron. To increase the peak beam intensity from 10mA to 40 mA, we plan to replace the front end system of the linear accelerator. Meanwhile, a superconducting linear accelerator will be implemented to boost the beam energy from 80 MeV to 300 MeV. This paper presents the upgraded linac lattice design and corresponding commissioning results developed for high intensity beam operation.
