摘要
White Rabbit(WR)is a technology that provides sub-nanosecond synchronization over Ethernet networks^([1,2]).We develop the timing system for HIAF accelerator based on White Rabbit technology.The WR timing system network is mainly composed of White Rabbit master nodes(WRMN),White Rabbit switches,and White Rabbit nodes.Among them,the WRMN is mainly used for generating accelerator's acceleration sequence commands,distributing commands and other functions,the WRWN is a core component of the WR network.In order to facilitate the physical control software to con gure the WR network,the WRMN needs to provide an EPICS PV interface.
