Introduction to IHEP

The Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences (CAS), founded in 1973, 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. With campuses in Beijing and in Dongguan, Guangdong Province, IHEP currently has a staff of about 1400, of whom roughly 1100 are research and technical personnel. Xie Jialin, Academician of Chinese Academy of Sciences, was awarded China Top Scientific and Technological Award in 2011. In 2014, Wang Yifang was jointly awarded the W. K. H. Panovsky Prize in Experimental Particle Physics and in 2015, Wang Yifang and the Daya Bay Collaboration were jointly awarded the 2016 Breakthrough Prize in Fundamental Physics.

IHEP manages a number of China’s major scientific facilities, including the Beijing Electron Positron Collider (BEPC), the Beijing Spectrometer (BES), the Beijing Synchrotron Radiation Facility (BSRF), the International Cosmic-Ray Observatory at Yangbajing in Tibet, the Daya Bay Reactor Neutrino Experiment, the China Spallation Neutron Source, the Hard X-ray Modulation Telescope (HXMT), the Accelerator-driven Sub-critical System (ADS) and the Jiangmen Underground Neutrino Observatory (JUNO). In addition, there are several laboratories and research centres which are partially or fully supported by the institute itself, four CAS key laboratories directly supported by the CAS, and one laboratory supported by the city of Beijing.

Since the first successful e+e- collisions at the Beijing Electron Positron Collider (BEPC) in October 1988, IHEP has become established as one of the world’s major High Energy Physics (HEP) laboratories. Several important physics results were obtained with BEPC by the Beijing Spectrometer (BES) collaboration, such as the precision measurement of the τ lepton mass, direct and model-independent measurement of the Ds meson decay constant, precision measurement of the resonance parameters of the J/ψ, and precision measurements of hadron cross-sections (R values) for electron-positron annihilations in the 2-5 GeV energy region. With the upgraded accelerator (BEPCII), the BESIII Collaboration has been able to obtain many important new results, such as the discovery of charged charmonium Zc (3900) and the first observation of many new light hadrons.

IHEP also makes full use of its advanced accelerator and analytical nuclear facilities to enable studies in other fields of science, including condensed-matter physics, chemistry, life sciences, materials science, nano-science and environmental science. The BSRF has 5 insertion devices and 14 beamlines with experimental stations, allowing about 300-400 experiments to be carried out each year by nearly 100 national research institutions. The BSRF is also used for interesting studies in the fields of protein crystallography, nano-materials, X-ray phase contrast imaging and experimental techniques. With this facility, a number of high-profile results have been obtained, including the protein structure of SARS, the structure of protein complexes in the light-harvesting membranes of spinach and other higher-order plants, and the mechanism of arsenic treatment for leukemia.

IHEP has actively pursued non-accelerator-based particle and astroparticle physics research. The Daya Bay Reactor Neutrino Experiment went into operation in late 2011. In March 2012, the discovery of a new type of neutrino oscillation was announced with a precise measurement of the unknown neutrino mixing parameter θ13. This is a very significant result and was selected as one of the top ten Breakthroughs of the Year 2012 by Science.

Another internationally renowned experiment is the cosmic-ray observatory at Yangbajing, Tibet, at an altitude of 4,300 meters above sea level. There are two large air shower arrays: the Sino-Japanese ASγ experiment, commissioned in 1990, and the Sino-Italian ARGO-YBJ experiment, started in 2001.

IHEP is also engaged in space-borne experiments. Examples include a γ-ray burst detector on board the Shenzhou II test flight of the Chinese manned space program, and an X-ray spectrometer for the Chinese moon exploration program. The Hard X-ray Modulation Telescope (HXMT), which was officially approved in 2010, is the first dedicated space science satellite in China, and will be launched in 2015.

IHEP is also expanding its user facilities from X-rays to neutrons. A new facility, the China Spallation Neutron Source (CSNS), is now under construction in Dongguan, Guangdong Province, and will be one of the world's four spallation neutron sources.

Over the years, IHEP has developed strong cooperative ties with the international high energy physics community. The US is one of China’s most important and longstanding international partners in high energy physics, with collaboration between IHEP and US institutions going back over thirty years.  Collaborative efforts have been concentrated on major projects such as the BEPC and BEPCII, the BES collaboration and the Daya Bay Reactor Neutrino Experiment.

IHEP has a long history of extensive cooperation with the European and Asian high energy physics communities, including CERN, INFN, DESY, CNRS, RAL, KEK and PLS. IHEP hosts the BESIII and Daya Bay Collaborations with the participation of hundreds of scientists from dozens of countries, and also hosts the Sino-Japanese and the Sino-Italian Cosmic Ray Collaborations in Tibet. IHEP also takes part in major experiment collaborations at other labs, including AMS, ATLAS, BELLE & BELLE II, CMS, EXFEL, ILC and PANDA.

IHEP is authorized to confer Masters and Ph.D. degrees in theoretical physics, particle and nuclear physics, condensed matter physics, optics, inorganic chemistry, nuclear technology and applications, and applied computer technology.  There are currently over 470 postgraduate students and 50 post-docs working at IHEP.

The Multi-disciplinary Research Division (MRD) was established in 2006, comprising a synchrotron radiation laboratory, nuclear analysis techniques laboratory and free electron laser laboratory. It has three scientific research facilities open for users, including the Beijing Synchrotron Radiation Facility (BSRF), Beijing Intense Slow Positron Beam Facility and Beijing Free Electron Laser Facility (BFEL). Scientists and technicians in the MRD are in charge of the operation, maintenance and improvement of all the facilities. The MRD also develops multidisciplinary research and applications based on on these research facilities and nuclear techniques. The High Energy Photon Source (HEPS), with storage ring electron energy of 6 GeV and natural emittance of better than 0.1 nm×rad, is currently being planned. HEPS is designed to have a circumference of 1296 meters with more than 80 high-performance beamlines. At present, a of HEPS R&D project (High Energy Photon Source Test Facility, HEPS-TF) is underway, and is one of the major national scientific and technological infrastructure projects in China's 12th Five-Year Plan.
