Development of CSNS white neutron source beamline control system

China Spallation Neutron Source (CSNS) white neutron source beamline mainly consists of one neutron beam window, one neutron beam shutter, two neutron beam collimators and some vacuum ducts. To guarantee a safe, stable, and reliable operation for the CSNS white neutron source beamline, a CSNS white neutron source beamline control system was developed under the Experimental Physics and Industrial Control System (EPICS) software framework. The system mainly consists of three subsystems: the motion control system of the neutron beam window, the neutron beam shutter and the neutron beam collimators; the vacuum control system; the control room. The remote monitoring and control of the main equipments of the CSNS white neutron source beamline was realized. The test results show that the system has the characteristics of high stability, high reliability and friendly operator interface, which satisfactorily meets operational needs.
