From December 3rd to December 6th, the Institute of Modern Physics, Chinese Academy of Sciences performed the first random cooling commissioning experiment on the Lanzhou Heavy Ion Research Facility (HIRFL) experimental ring (CSRe) and successfully realized the 12C6+ (380MeV/u) beam flow. Vertical and horizontal cooling. After more than five years of research in theory, model, polar plate structure, and radio frequency electronics, the Institute of Modern Physics mastered this cooling technology, which won the Nobel Prize in physics, on the basis of extensive international cooperation. The CSR has laid a solid foundation for relevant high-precision secondary beam physics experiments. In 1983, CERN's proton-antiproton colliders used random cooling technology to obtain high-quality, high-strength protons and anti-proton beams, and finally found intermediate vector bosons. S. Van der Meer, inventor of random cooling technology, and C. Rubbin, who heads the construction of the proton-antiproton collider, won the 1984 Nobel Prize in physics. At present, only the United States, Germany, Switzerland and Japan have mastered and successfully applied this technology. The establishment of a random cooling system in CSRe enables high-efficiency cooling of secondary beams with large momentum divergence and large emittance. In combination with electronic cooling, the cooling time of secondary beams with large emittance can be greatly reduced (cooling time can be reduced from minute to minute. Reduced to the second order, so that a high-quality secondary beam can be obtained in a short time for high-precision nuclear physics experiments. Based on theoretical and simulation calculations, the Impedance and Beam Feedback Group of the Institute of Modern Physics independently developed a wide-bandwidth, high-gain detection plate and a nanosecond-order RF signal transmission system. The random cooling hardware was set up. In the first beam debugging experiment, The rapid cooling of the beam in three directions, vertical, horizontal and vertical, was successfully achieved. The successful development of the random cooling system makes it possible to carry out experiments such as short-lived nuclear mass and beta decay measurements, and is of great significance to the development of China's atomic physics and nuclear physics. At the same time, it also marked the “12th Five-Year Plan†major scientific project of the Institute of Modern Physics—a key technology of the HIAF (Radioactive Heavy Ion Accelerator) (HIAF)—random cooling technology completed the pre-research work.
