Established in February 2013, the Dongguan Campus is a branch of IHEP dedicated to building and operating the China Spallation Neutron Source (CSNS), a large-scale scientific facility being constructed in Dalang Town, Dongguan City, Guangdong. 

The Dongguan Campus consists of three research divisions, the Division of Accelerator Technology, Division of Neutron Science, and Facilities Operation and Management , as well as eight other administrative offices. There are currently over 300 staff and students based at the Dongguan Campus.

The major mission of the Dongguan Campus is to finish the construction of the CSNS, and to develop the CSNS into not just a research center for neutron and proton sciences, but also a world-class high-performance platform for multidisciplinary research. The CSNS will be the first spallation neutron source in a developing country, and one of four spallation neutron sources in the world. 

It is expected that the construction and operation of CSNS will have positive effects in promoting science and technology. Thus, the Dongguan Campus is committed to serve as a bridge between the CSNS and the local government, and provide solid support for industrial development and technological innovation.
