Proton therapy serves as a new level of tumor radiotherapy technology. It has the characteristics of good therapeutic effect, small side effects, and rapid patient recovery. It is an excellent way to treat tumors internationally. Due to the high cost of introducing proton and heavy ion equipment and operating costs, the core technology is monopolized overseas, China lacks proton and heavy ion medical and health equipment, and the development and industrial development and application promotion of independent patented domestic proton and heavy ion equipment has broad market prospects.
The proton therapy system research team of the Hefei Research Institute of the Chinese Academy of Sciences has made groundbreaking progress in several important aspects such as component development, integrated assembly technology, and system software joint debugging and testing. At present, the world's most compact nanotube rotating proton and heavy ion system accelerator has been successfully developed, thus successfully generating a 200MeV proton beam and achieving independent controllability at the technological level of compact nanotube network accelerators. The current intensity of the superconducting magnet has reached 140A/mm2, which is three times the magnetic field of similar equipment around the world; the electric field application has reached the world's highest level of 175kV/cm; the network accelerator has achieved the maximum magnetic field intensity of 3.0 Tesla;
The diameter has become smaller by 25, only 2.2 meters, and the total weight does not exceed 50 tons. After several months of system adjustments, the beam generation in the diagnostic room was successfully completed, solving the problem of combining beam delivery with precise conformal treatment. The first domestically produced high-purity graphite energy reducer successfully developed and designed can realize high-precision adjustment of kinetic energy of 70-185CeV, with a matching range of 4.1g/cm2-22.7g/cm2 and a precision of 0.5CeV. Completed the development and design of the first supercritical extraction externally cooled diode system in my country, and completed the design of a miniaturized nanotube rotation system, significantly reducing the cost of development and construction.
The Hefei Municipal Government jointly established Hefei Zhongke Ion Company to conduct independent research and development of domestic nanotube rotary proton and heavy ion system software and promote the development of the proton medical and health equipment industry. The Institute of Plasma Research of the Chinese Academy of Sciences has built and operated a number of core technologies, promoted the application and promotion of large-scale scientific research projects, promoted the application of medical and health equipment such as nanotubes, magnetic fields, and cryogenics, and served the "Healthy China" strategy. and the development trend of the domestic health industry, serving the main frontier of economic development and the life and health of the people.
