The Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences (CAS) is a premier research institute dedicated to fundamental and applied research in high-energy physics, advanced accelerator technology, and radiation applications. IHEP is committed to becoming a world-leading center in high-energy physics and a large-scale, multidisciplinary research hub.

In 2013, IHEP established its Dongguan Research Division in Guangdong Province, which is responsible for the construction and operation of the China Spallation Neutron Source (CSNS), a major national science and technology facility. CSNS is a high-performance pulsed spallation neutron source serving as an open platform for cutting-edge fundamental research and applied studies in many disciplines. The first phase of construction was completed in 2018, and 11 neutron instrument beamlines are now in operation. In April 2024, the second phase project (CSNS-II) was launched, which will add 9 new specialized scient...
