China / Shanghai Two calls each year: March 31 and September 30 Shanghai Synchrotron Radiation Facility (SSRF)
Regular user proposals undergo two centralized reviews each year. Approved projects can normally use allocated beamtime in multiple sessions over two years. Confirm beamline capability, measurement mode, and sample safety before applying.
Spring-round beamtime normally begins in July of the same year; autumn-round beamtime normally begins in January of the following year. Hazardous, biosafety-sensitive, or special-environment samples require additional technical review time.
- XAFS, micro-XRF, and micro-XANES
- XRD, SAXS, and hard X-ray imaging
- Infrared microspectroscopy and soft X-ray spectroscopy
China / Hefei Accepted year-round; reviewed quarterly Hefei Synchrotron Radiation Facility (HLS / NSRL)
User proposals are accepted year-round and reviewed quarterly. The facility has particular strengths in soft X-rays, infrared microspectroscopy, photoelectron spectroscopy, and surface science.
Wet, microbial, or non-conductive environmental samples may require drying, freezing, or dedicated sample cells. Confirm sample state and vacuum compatibility with the beamline early.
- Infrared microspectroscopy
- Soft X-ray absorption spectroscopy and imaging
- Photoelectron spectroscopy and surface-reaction analysis
Taiwan, China / Hsinchu Two calls each year, commonly in February and August Taiwan Photon Source / Taiwan Light Source (NSRRC)
General-user proposals are commonly called twice per year for the two half-year operating cycles, covering XAS, micro-XRF, X-ray microscopy, scattering, and soft X-ray experiments.
Beyond the proposal itself, confirm travel approvals and sample transport requirements early. Soil, tailings, microbial, and metal-bearing samples require particular attention to declaration and quarantine conditions.
- XAS / XAFS and micro-XRF
- X-ray microscopy, tomography, and nanoscale imaging
- SAXS / WAXS and soft X-ray spectroscopy
Canada / Saskatoon Two calls each year, commonly in February and August Canadian Light Source (CLS)
General User Access runs two calls each year. New projects are normally active for two years, while a specific beamtime request is still required for each operating cycle. Some beamlines support mail-in or remote experiments.
Confirm STXM or other measurement modes, sample transport, and research-security requirements with the beamline before applying. Mail-in and remote access may be preferable for cross-border samples.
- STXM and soft X-ray spectroscopy
- Mid-infrared microspectroscopy
- XAS, imaging, and microscale environmental characterization
China / Beijing Huairou Regular, rapid, and special calls are released in batches High Energy Photon Source (HEPS)
HEPS is a new high-energy synchrotron facility suited to high-brightness, high-energy, high-spatial-resolution, and in situ experiments. Beamlines and measurement modes are opened in phases.
Contact the beamline to confirm available modes, sample dimensions, and expected signal strength before submitting a user proposal. Approved users apply separately for beamtime and technical safety review.
- Micro-XRF and micro-XANES
- High-energy total scattering and PDF
- Nanoscale imaging and in situ reaction studies
China / Beijing User proposals and beamtime requests follow operation notices Beijing Synchrotron Radiation Facility (BSRF)
Users first apply for a project, then request specific beamtime according to the operating schedule. Beamtime for openly published research is generally free, and projects are normally valid for two years.
Contact the beamline one to two months before the proposed experiment to confirm feasibility, sample numbers, and safety requirements for XAFS, imaging, micro-XRF, or soft X-ray work.
- XAFS / XANES / EXAFS
- Micro-XRF and X-ray imaging
- Soft X-ray absorption spectroscopy
