The dawn of a new era in scientific exploration is upon us as China prepares to unveil the High Energy Photon Source (HEPS), the world’s brightest X-ray light source. Located just north of Beijing, the facility promises to revolutionize research in materials science, biomedicine, and physics. With beams that are a trillion times brighter than the sun’s surface, HEPS will allow scientists to explore the microscopic world with unprecedented detail. This groundbreaking project not only marks a milestone in X-ray technology but also underscores China’s commitment to advancing scientific infrastructure.
Unveiling the Brightest X-Ray Light Source
HEPS is designed to generate beams of light that are a trillion times brighter than the sun’s surface, offering researchers unparalleled detail and precision. The facility, located approximately 30 miles north of Beijing, is expected to begin operations later this year. Once operational, HEPS will power cutting-edge research, allowing scientists to observe and manipulate matter at a microscopic level.
The civil construction of HEPS was completed in August 2024, and the facility has since entered the light commissioning phase. This crucial step involves testing and fine-tuning the system with real photon beams, ensuring readiness for trial operations. According to Pan Weimin, project director at the Chinese Academy of Sciences’ Institute of High Energy Physics, “Once HEPS reaches its designed brightness, it will be capable of revealing the microscopic world in unprecedented detail.”
Such breakthroughs promise to redefine scientific exploration, offering new insights into the atomic and molecular structures that underpin our world.
Advancing X-Ray Technology
The development of light sources has been pivotal in scientific research since the 1970s, with over 70 facilities built worldwide to date. These machines accelerate electrons to near-light speed, utilizing powerful magnets to guide them. When electrons alter their trajectory, they emit high-energy light particles, enabling researchers to analyze molecular structures.
HEPS stands out as a fourth-generation light source, boasting ultra-low-emittance storage rings that maintain electron beam stability and focus. This technology allows scientists to observe smaller structures, faster processes, and weaker signals with remarkable precision. The facility’s brightness is anticipated to be significantly higher than existing counterparts, such as the Extremely Brilliant Source in France. This capability will allow for groundbreaking discoveries in materials and biological systems at an atomic level.
Pan Weimin and his team have emphasized the importance of independent innovation in the development of HEPS. The introduction of a novel injection and extraction method enhances efficiency and minimizes environmental impact. By recycling low-energy electron beams and merging them with fresh particles, HEPS conserves energy and improves beam quality.

A Key Addition to China’s Scientific Infrastructure
HEPS represents a significant national investment in science, with a project budget of 4.8 billion yuan (US$665 million). The construction, which began in June 2019, is expected to take just over six years. The completion of the accelerator and the first set of 14 user beamlines marks a major milestone in this ambitious project.
This new facility will complement the Shanghai Synchrotron Radiation Facility (SSRF), China’s premier third-generation light source. Since its launch in 2009, SSRF has supported thousands of experiments annually, hosting over 10,000 researchers. However, the growing demand for beamline access has led to long wait times, a challenge HEPS is poised to address by providing additional capacity.
With HEPS nearing completion, China is set to lead the world in next-generation light source technology, pushing the boundaries of what scientists can achieve in various fields.

Implications for Global Scientific Research
The completion of HEPS signifies a major leap forward for global scientific research, particularly in fields requiring detailed atomic-level analysis. The unprecedented brightness and precision of HEPS will enable breakthroughs across various disciplines, from developing new materials to advancing our understanding of biological processes.
This cutting-edge facility represents a powerful tool for scientists worldwide, offering insights that were previously unattainable. As researchers begin to unlock the potential of HEPS, they are likely to make discoveries that could revolutionize technology, medicine, and our understanding of the universe.
As China continues to lead in scientific innovation, the global research community stands to benefit from the advancements made possible by HEPS. The facility’s contributions are poised to extend beyond national borders, impacting scientific progress worldwide.
As we anticipate the transformative capabilities of the High Energy Photon Source, we are left to wonder: What groundbreaking discoveries will scientists unlock with this unprecedented tool, and how will they reshape our understanding of the universe?
