China News Agency, Beijing, January 14 (Reporter Sun Zifa) The reporter learned from the Institute of High Energy Physics of the Chinese Academy of Sciences (Institute of High Energy, Chinese Academy of Sciences) on the 14th that the high-energy synchrotron light source (HEPS), a large scientific device undertaken by the Institute, has recently obtained a major Progress - With the completion of the sealing of the last section of the bellows of the HEPS intensifier on the afternoon of January 13, the intensifier was fully connected.
Pan Weimin, chief commander of the HEPS project and researcher at the Institute of High Energy, Chinese Academy of Sciences, announced the closure and pointed out that the full line penetration of the HEPS intensifier marks that the intensifier has completed the online equipment installation work and entered the equipment debugging stage.
HEPS construction has taken another big step forward.
The intensifier is an important part of the HEPS accelerator, with a circumference of about 454 meters. It is mainly responsible for accelerating the electron beam from 500 MeV (megaelectron volts) to 6 GeV (giga electron volts), and at the same time receiving the beam drawn by the storage ring at 6 GeV. The charge accumulation is completed, and the beam is extracted and injected into the storage ring in a timely manner under the condition of extraction.
The installation tasks of HEPS intensifier equipment include pre-collimation, tunnel installation, precise alignment, vacuum connection and packaging, etc., with a tight schedule and heavy tasks.
After the HEPS intensifier is successfully debugged, it will become the world's first intensifier with high-energy reinjection function and beam accumulation.
It is understood that the HEPS overall building looks like a magnifying glass, implying it is a sharp tool for detecting the microscopic world.
After completion, HEPS will be the first high-energy synchrotron radiation source in China and one of the fourth-generation synchrotron radiation sources with the highest brightness in the world.
The main construction contents of HEPS include accelerators, beamline stations and auxiliary facilities, etc., and the construction period is 6.5 years.
The large scientific installation started construction in Beijing Huairou Science City in June 2019. It is a major national science and technology infrastructure built during China's "13th Five-Year Plan" period to provide a technical support platform for the country's major strategic needs and cutting-edge basic scientific research. The core device of Huairou Science City jointly built by the Chinese Academy of Sciences and Beijing is also the most important major scientific and technological infrastructure of Beijing Huairou Comprehensive National Science Center.
