Description

The beam commissioning of the CSNS RCS began in 2017. Over the years, the CSNS RCS has achieved step-by-step progress, including successful beam accumulation, acceleration to 1.6 GeV, and a gradual increase of beam power from 10 kW to over 185 kW on target.

Currently, the upgrade project of the CSNS (CSNS-II) is ongoing. The primary goal of CSNS-II is to further increase beam power to 500 kW. To achieve this, studies are being conducted on various aspects, including new injection system commissioning, longitudinal dynamics optimization, beam loss optimization, closed orbit correction, and using advanced techniques like Bayesian optimization.

This talk give a summarize of the high intensity beam commissioning studies performed on the CSNS RCS, covering both the achievements to date and the ongoing research toward the CSNS-II power upgrade.
