China’s latest High Energy Photon Source (HEPS) will be the first fourth-generation synchrotron light source in Asia. Its operation will start by the end of this year.

High Energy Photon Source (HEPS) Synchrotron

  • This advanced facility will emit extremely bright X-rays, which will significantly enhance various scientific research capabilities.
  • This HEPS is designed to accelerate electrons up to energies of 6 gigaelectron volts.
  • The high energy X-rays emitted in this process can penetrate deeply into samples and produce intricate details on the nanometer scale.
  • Its time resolution will be 10,000 times better than that of the third generation synchrotron.
  • Older synchrotrons require larger or larger samples that are difficult to produce, making it nearly impossible to study small protein crystals.
  • However, the strong X-rays from the High Energy Photon Source (HEPS) will be powerful enough to allow even the smallest samples to be analyzed in detail.

Synchrotron light source

  • Synchrotron Light Source is a machine which produces electromagnetic radiation (like X-rays, visible light etc.) for scientific and technical purposes. It is usually in the form of a storage ring.
  • The High Energy Photon Source (HEPS) is recognized as the brightest synchrotron X-ray source in Asia.
  • Synchrotrons use electricity to produce intense beams of light. These rays are one million times brighter than the Sun.
  • Fourth generation facilities such as the High Energy Photon Source rely on an array of multi-band achromat lattice magnets to generate X-ray beams, which are narrower than the X-ray beams produced by the previous generation and therefore more Are shiny.
  • In 2025, the High Energy Photon Source will be able to choose from 14 beamlines for experiments in disciplines including biomedicine, energy, advanced materials and condensed-matter physics.
  • The High Energy Photon Source is expected to accommodate 90 beamlines in the coming year.
  • Its (HEPS) potential impacts will affect every scientific field except mathematics.
