The Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences (CAS) was founded in February 1973. Its predecessor,the Institute of Modern Physics, was founded in 1950, later renamed the Institute of Physics and then the Institute of Atomic Energy, before IHEP was established from Division One of the Institute of Atomic Energy. IHEP is a comprehensive research base for particle and astroparticle physics, accelerator physics and technology, radiation technologies and applications, as well as for nuclear analytical techniques and interdisciplinary research.
