Description
China Spallation Neutron Source (CSNS) accelerator complex will employ a new superconducting accelerating section to achieve high beam power. To protect the superconducting cavity from contamination, the second phase of the CSNS superconducting linac section will adopt laser stripping technology for transverse distribution measurements of the negative hydrogen beam at nine stations. In 2024, a laser wire(LW) prototype was installed to measure the profile of the 80MeV H- beam. This paper describes the commissioning results of this LW prototype, including the optimization before scanning, and data analysis.
