Institute of Modern Physics, Chinese Academy of Sciences

The Institute of Modern Physics ( IMP ) of the Chinese Academy of Sciences was founded in l957. After a half century of development, IMP has become the most important research center for heavy ion sciences in China. We have established active and fruitful collaboration with more than 40 institutions worldwide. IMP operates the Heavy I...

  • Scientists Reveal Enzymatic Hydrolysis Process of Alkali Pretreated Straw

    Researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences have made progress in the study of enzymatic hydrolysis process of alkali pretreated straw lately. The research provides insight into the structural changes and visualization of the hydrolysis process. These findings will help to design plant cell structures and plant tissues at the organization level, and reduce the natural recalcitrance of lignocellulose, thereby enhancing the overall biomass conversion efficiency.

  • A New Operation Mode of HIRFL Tested Successfully

    On January 7, the Heavy Ion Research Facility in Lanzhou (HIRFL) provided the beam for users by the combination of three different types of accelerators. By the new operation mode, it is possible to obtain highly-charged heavy ion beams with the energy higher than other modes operated previously. The new operation mode will greatly improved the efficiency and capacity of HIRFL.Learn more

  • First Slow Extraction of Beam with Maximum Magnetic Rigidity at HIRFL-CSRm

    On January 1,the beam with the energy of 150 MeV/u was extracted smoothly within 3 seconds from the main cooling storage ring (CSRm) at the Heavy Ion Research Facility in Lanzhou (HIRFL). It is the first time that the beam with the maximum magnetic rigidity has been extracted by the slow extraction system at HIRFL-CSRm. This great improvement will benefit users in material research, bioscience and other application science at HIRFL. Learn more
