Description

The China Spallation Neutron Source(CSNS) is the first large-scale pulsed spallation neutron source in China and the fourth of its kind in the world. It is a large multidisciplinary user facility. The facility passed national acceptance and officially opened for operation in 2018. It has been in operation for seven years. During this period, the beam power has continually increased, and both the beam runtime and availability have gradually improved. In the 2023-2024 period, it achieved a maximum beam on target time of 5,433 hours and the highest beam availability of 97.4%, which are the best among similar international facilities. This article will comprehensively introduce the operational performance of the accelerator over the past seven years, including annual beam runtime, beam availability, and statistics on hardware system downtime. Additionally, it will briefly discuss some measures taken to enhance operational reliability, including hardware upgrades, software optimizations, and maintenance strategies.
