National Science & Technology Infrastructure

（1） High Energy Photon Source (HEPS) 

High Energy Photon Source (HEPS) is an important platform-supported original and innovative research facility in the fields of basic science and engineering science.HEPS will not only be the 1st high energy synchrotron radiation source in China, but also a world leading high energy synchrotron radiation source platform. HEPS will consist of accelerator, beamlines and experimental stations. Up to 90 high-performance beamlines and experimental stations could be constructed in HEPS, which will provide X-ray energy exceeding 300keV, with nano-scale spatial resolution, ps-scale time resolution and meV-scale energy resolution. HEPS can meet the requirements in the frontier research of non-equilibrium, non-linearity, local and individuals inside complex systems. Once completed, HEPS will satisfy well enough the research demands in the frontier of science and engineering fields, and will provide strong supports for promoting scientific and technological innovation abilities in basic scientific research.

（2）Synergetic Extreme Condition User Facility (SECUF) 

SECUF is a large scientific experimental facility consisting of a series of supporting cluster equipment which integrates low temperature, high pressure, strong magnetic field, ultra-fast light field, etc. It includes extreme experimental condition generation systems, sample characterization and measurement systems under extreme conditions, and support systems that meet the requirements of development, upgrade, maintenance and operation of the above systems. 

The facility aims to be "the world's first user facility that integrates extreme conditions like ultra-low temperature, ultra-high pressure, strong magnetic field and ultra-fast light field, etc.". It will greatly enhance China's comprehensive strength in basic research and applied basic research in material science and related fields. It will also enable China to make world-class research achievements in the discovery of new high-temperature superconductors, the breakthrough of unconventional superconducting mechanism and quantum computing core technology, the ultra-fast regulation of physical properties and the real-time imaging of lattice vibration,etc.  

（3）The Earth System Numerical Simulation Facility 

The Earth System Numerical Simulation Facility, named "EarthLab", is a numerical simulation system of the whole Earth system with matched software and hardware. The construction is located in Huairou Science City of Beijing, and completed in 2021.  

It can help explore the dynamical, physical, chemical, and biological processes of each sphere of the earth system, and the impact of interaction among various spheres on the whole earth system as well as the regional environment over China; integrate simulations and observed data to improve the accuracy of forecasting; improve the prediction and projection skills for climate change and air pollution; provide a numerical simulation platform to take Earth system research in China to the top level internationally; and support China's disaster prevention and mitigation, climate change, and atmospheric environment governance, along with other major issues.  

（4）National Multimode Trans-Scale Biomedical Imaging Center 

This National major scientific and technological infrastructure will unprecedentedly merge optical, acoustic, electrical, magnetic, nuclear, electronic and other imaging modalities, provide abilities of life science research that cover ten orders of magnitude in space and time. It will provide open sharing services for national basic scientific research, technology industries and clinical applications, and provide strategic support for national major scientific programs and biomedical imaging equipment industry.  

（5）Ground-based Space Environment Monitoring Network –GSEMN (The second phase of Meridian Project) 

The Ground-based Space Environment Monitoring Network is one of the Top Ten priority construction projects in “13th Five-Year plan”. It based on the stations distributed along the latitude of 30N, 40N and the longitude of 100E, 120E will build a well-shaped ground-based monitoring network which can cover China’s major regions. The overall framework of GSEMN includes three parts, as follows. 

“One Chain”: It will also build up the capability of monitoring the whole chain from the Sun to Earth by setting up a series of advanced solar-interplanetary monitoring facilities. 

“Three Networks”: The project will use different kinds of monitoring facilities to achieve the networked capability of monitoring ionosphere, atmosphere and geomagnetic field in China’s region. 

“Four Focused Regions”: It will deploy the international advanced large monitoring facilities in the four key regions including the high latitude region, northern mid-latitude region, southern low-latitude region and the Qinghai-Tibet Plateau in order to detect the space environment subtly in those regions.
