Proton therapy acts as a new level of tumor radiotherapy technology, with good therapeutic effect, small adverse reactions, fast repair of patients and other characteristics, is an excellent way to treat tumors internationally. Because of the introduction of proton heavy ion equipment and high operating costs, the core technology is monopolized by overseas, China lacks proton heavy ion medical and health equipment, independent patents for the development of domestic proton heavy ion equipment and industrial development and application of the promotion of market prospects.
Hefei Research Institute of Chinese Academy of Sciences, proton therapy system research team, in the development of components, integrated assembly process, system software coupling testing and several other important aspects of the groundbreaking progress. At this stage, the world's most compact nanotube rotary proton heavy ion system gas pedal has long been successfully developed, and therefore successfully generated 200MeV proton beam current, completed the compact nanotube network gas pedal technology level of independent control. The superconducting magnet's current strength has achieved 140A/mm2, which is 3 times of the magnetic field of similar machines and equipments in the world; the use of electric field has achieved 175kV/cm international maximum level; the network gas pedal has accomplished 3.0 Tesla's car maximum magnetic field strength;
The diameter has become 25% smaller, only 2.2 meters, and the total weight is not more than 50 tons. After several months of system software adjustment, obtained successfully completed the diagnostic room beam current generation, solved the beam current transmission and precise conformal healing close combination of the difficulties. Developed and designed successfully the first domesticated high purity graphite energy reducer, which can complete the high precision adjustment of kinetic energy of 70-185CeV, with the matching range of 4.1g/cm2-22.7g/cm2, and the precision of 0.5CeV. Completed the development of the first supercritical extraction of externally-cooled diode iron system software development and development and design, and completed the miniaturized nanotube rotation system software design scheme, which greatly reduced the development and design of the system software. Design program, significantly reducing the cost of development and construction fees.
Hefei government departments together to establish the Hefei Zhongke Ion Company, to carry out independent research and development of domestic nanotube rotating plasmonic heavy ion system software, and to promote the development of plasmonic medical and health machinery and equipment industry. The Chinese Academy of Sciences Plasma Institute of basic construction operation of a number of core technologies, promote the application of large and medium-sized scientific research engineering design to promote the use of nanotubes, magnetic fields, ultra-low temperature and other medical and health machinery and equipment, service projects in ? Physical and mental health of China? strategy and the development trend of domestic health industry, service projects in the main economic development and the life and health of the people.
