The run management system for CSNS

Abstract

The China Spallation Neutron Source (CSNS) accelerator consists of an 80-MeV H-linac, a 1.6-GeV rapid cycling synchrotron (RCS) and two beam transport lines. The designed proton beam power is 100 kW in Phase-I. The CSNS accelerator can operate in different beam modes and beam destinations, and for each beam destination, the beam power must be strictly restricted; meanwhile, the linac and the RCS may operate independently during the commissioning stage. To satisfy these operation requirements, the run management system (RMS) was designed and deployed for CSNS. The run management system, including a hardware layer and a software layer, operates on the top level of the global control system. RMS coordinates the machine protection system, personnel protection system, timing system and other systems, to set and publish the machine states and machine modes, to verify beam parameters and to permit the beam extraction from ion source. The RMS has been operating for more than one and half years and has played an important role during the commissioning and operation of CSNS facility. This paper will introduce the design and implementation of the RMS for CSNS.
