  The China Spallation Neutron Source (CSNS) is an accelerator-based high-power project currently under planning in China. For the similarities between the CSNS and the U. S. Spallation Neutron Source (SNS), the SNS control framework will be used as a model for the machine controls. And the software framework used at SNS, XAL, is a natural choice for the CSNS. This paper provides a controls overview and progress. Also, the technical plan, schedule, and personnel plan are discussed.

  The database of the China Spallation Neutron Source (CSNS) Accelerator is designed to store machine parameters, magnet measurement data, survey and alignment data, control system configuration data, equipment historical data, e-logbook, and so on. It will also provide project management quality assurance, error impact analysis, and assembly assistance including sorting. This paper introduces the construction and application of the database for CSNS. Details such as convention name rules, database model and schema, interface of import and export data, and database maintenance will be presented.

  The magnet power supply ramping synchronously is a fundamental procedure of the energy ramping of the BEPCII storage ring. The BEPCII has been put into synchrotron radiation operation (SR) (2.5GeV) research for 2 months after beams were successfully running in the Storage Ring with good beam performance. A software-based synchronization of the DAC setting on the power supplies is developed to achieve the relative magnet power supplies in the synchrotron ring ramped to the designed current synchronously. This paper introduces the schemes developed to perform energy ramping in the BEPCII storage ring and reports on the result of the operation carried out so far.

  The control network of the BEPCII is divided into two separate different subnets. In order to access IOC PVs between the separate subnets as well as IOC PVs from the campus network, we adopt EPICS CA gateway in the BEPCII network. This paper describes the EPICS CA gateway employment and network management in the BEPCII .
