Description
The first phase of the China Spallation Neutron Source (CSNS) project aims to accelerate negative hydrogen ions to 80 MeV using a linear accelerator. Subsequently, these negative hydrogen ions are converted into protons after stripping, and then injected into a rapid cycling proton synchrotron. The proton beam is further accelerated to an energy of 1.6 GeV and guided through a beam transport line to a tungsten target, where spallation reactions gen-erate neutrons. With the initiation of the Phase II project of the China Spallation Neutron Source (CSNS II), the target power is anticipated to increase significantly to 500 kW in the future. Upgrading the existing 32 sets of BPM electronics on the Rapid Cycling Synchrotron (RCS) ring is essential to accommodate the enhanced beam power and fulfill the new requirements of the beam measurement. This paper focuses on the novel design and validation of the BPM electronics, as well as the execu-tion of tests during beam operation.
