AMS Postdoctoral Research Positions at the Institute of High Energy Physics, Chinese Academy of Sciences

IHEP Introduction:

The Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences in Beijing is one of the largest and most prestigious research institutions dedicated to high-energy physics. With over 1500 full-time employees and more than 900 postdocs and graduate students, IHEP serves as a pivotal center for pioneering research in high-energy physics. The institute is committed to major scientific and technological explorations, as well as leading high-energy projects, driving relevant research fields forward. Furthermore, IHEP actively fosters partnerships and collaborations with universities and research institutions worldwide, enriching its contribution to the global scientific community.

AMS Experiment:

The AMS experiment is an international collaboration involving 60 universities from Europe, Asia, and the United States. AMS is a highly precise particle physics detector operating on the International Space Station (ISS), using the unique environment of space to study the universe with the purpose to search for antimatter and the origin of dark matter and to perform precision measurements of charged cosmic rays from primordial sources in space. AMS has collected over 230 billion cosmic ray events up to multi-TeV energies and will continue to collect and analyze an increasing volume of statistics at the highest energies. On December 31, 2021, the White House announced that the Space Station will be extended to 2030. The U.S. Department of Energy Blue Ribbon panel, chaired by Nobel Laureate Barry Barish, has reviewed the achievements of AMS and has recommended that AMS be upgraded to increase its acceptance by 300% as quickly as possible.

Job Opportunities:

Successful applicant will join the AMS group at IHEP, led by Professor Qi Yan, a former senior staff member at MIT for 10 years, who led the AMS detector software development and AMS data analysis. The IHEP AMS group has major responsibilities in the AMS upgrade by adding a new silicon tracker detector layer (L0) on top of the existing 9-layer silicon tracker detector, which is expected to be launched and installed in early 2026. The group is also responsible for overall AMS offline software development and maintenance (such as regular calibration/alignment for the AMS time-of-flight detector and silicon tracker detector) and AMS data analysis. Applicants can choose to work on the following topics:

1. AMS L0 Upgrade: Participate L0 detector construction, detector module optical survey, beam tests, and space operation. Major tasks include the development of L0 detector software, calibration, and alignment.

2. Development of the Advanced AMS Detector Reconstruction Algorithm, Calibration, and Related Software: (The development can be for any AMS sub-detector, including the silicon tracker, the time-of-flight detector, the calorimeter, the ring imaging Cherenkov detector, and the transition radiation detector).

3: Measurement of Cosmic Ray Spectra: AMS has precisely measured the spectra of 16 different cosmic ray nuclei and published a series of important physics results with percent-level precision. Future work includes the analysis of 12 high-charge heavy nuclei that AMS has not yet published. These results will provide unique insights into cosmic rays for the decades to come.

4: Search for Antimatter (Antihelium and Antinuclei) in Cosmic Rays and Other New Physics.

5: Cosmic Ray Nuclei Isotope Measurements: Successful candidates can be promoted to tenured faculty at IHEP after their postdoc, with opportunities to become a core member of the AMS international research team. Candidates can choose to be based either in Beijing or CERN, with a preference for Beijing. Those based in Beijing will have opportunities for short-term travel to CERN every few months.

Diversity and Inclusion:

IHEP values diversity and welcomes candidates from all backgrounds worldwide. Beijing, an international city, offers vibrant communities and international schools with complete education systems from kindergarten to high school. Proficiency in Chinese is not mandatory. We provide comprehensive logistical assistance for international candidates to help with relocation, living arrangements, and all other aspects of settling in Beijing.

Application Details:

The positions will be open continuously. The annual salary ranges from 400,000-600,000 RMB (approximately 56,000-83,000 USD) with sufficient financial support for research. Applications should include curriculum vitae and statement of research interests. Please also provide the names and contact details of three references who will supply letters of recommendation upon request.

For any questions regarding the application, please contact Professor Qi Yan at We look forward to your applications and to welcoming new talent to the IHEP AMS group.

The Institute of High Energy Physics (IHEP), a Chinese Academy of Sciences research institute, is China’s biggest laboratory for the study of particle physics. We want to understand the universe better at the most fundamental level—from the smallest subatomic particles to the large-scale structure of the cosmos. We also want to use the knowledge and technology that comes from our research for the good of humanity. As well as theoretical and experimental research into particle and astroparticle physics, we have a broad range of research in related fields such as accelerator technologies and nuclear analysis techniques. The institute also provides beam facilities for researchers in other fields of study.  

Why work for us
Working at IHEP are more than 1,400 full-time staff, 600 postdocs and graduate students. Particle physics is a very collaborative and international field, and we have partnerships and experiment collaborations with dozens of universities and research institutions across China and worldwide.

We have doctoral programs in six scientific fields, as well as engineering doctoral programs in nuclear technology and computer technology. We also offer five full-time professional master’s degree programs in engineering. For those at a later stage in their careers, we offer formal postdoctoral training in physics and in nuclear science and technology.        

Recruitment objectives
Based on the needs of the research areas and the disciplines development of IHEP, we are now publicly recruiting overseas outstanding talents and scholars of relevant disciplines who possess research abilities and innovation awareness.

What we are looking for
We are always looking for more scientists and engineers, at all career stages, to join us in exploring this amazing universe. Whether you are a student, postdoc or established career scientist, why not consider bringing your skills to IHEP? There are long- and short-term opportunities available in our world-class research programs, including high-energy physics, particle astrophysics, cosmology, synchrotron radiation, and advanced accelerator physics.
