Organizationally, IHEP is divided into one branch and seven research divisions, roughly corresponding to the main research themes.

Dongguan Branch

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.

Experimental Physics Division

The Experimental Physics Division (EPD) of IHEP is an established research center for experimental particle physics in China. It is also a development center for the technologies needed for particle physics experiments, including advanced detectors, electronics, high speed data acquisition and signal processing, and superconducting magnets. The EPD was responsible for the design and construction of the BEijing Spectrometer III (BES III) experiment and the Daya Bay Reactor Neutrino Experiment, which are now running. The Division is currently building the Jiangmen Underground Neutrino Observatory (JUNO), which expects to start data taking in 2020.

Particle Astrophysics Division

The Division is mainly involved in studies of the large-scale structure and evolution of the universe by observing cosmic rays. The Division undertakes many important research projects and international collaborations. The Hard X-ray Modulation Telescope (HXMT) is a collimated hard X-ray (20-200 keV) telescope with the highest sensitivity and spatial resolution power in the world. Its R&D started in March 2011, and will be launched in 2015.

Division of Nuclear Technology and Applications

The Division of Nuclear Technology and Applications focuses on the R&D of nuclear technology oriented by social and economic needs. It is also a platform of technology transfer for advanced accelerator and radiation technology. By actively attracting investment from society and working with industry, it is dedicated to promoting application and technology transfer. The division works on research of applied nuclear science, development of key components and instrumentation aimed for technology transfer. The division has also set up open platforms for molecular imaging research and nondestructive-testing services to meet society's needs.
