"The significance of our scientific research lies in the research and development of medical equipment that can be used and affordable by ordinary people." On the 6th, Yang Jiancheng, member of the CPPCC National Committee and deputy director of the Institute of Modern Physics of the Chinese Academy of Sciences, said in an interview with reporters that the demonstration project of the second generation medical heavy ion accelerator has begun to be constructed. Yang Jiancheng and his colleagues have developed an internationally leading medical heavy ion accelerator. That is truly a great power weapon. It is said to be large because the device itself is large enough. Its core component, the synchronous accelerator, has a circumference of about 56 meters and covers an area of over 6 acres; Speaking of its importance, the key lies in its abundant technological value - medical heavy ion accelerators utilize the characteristics of heavy ions to achieve precise targeted blasting of cancer cells, which is internationally recognized as one of the advanced treatment methods. Currently, only Japan and Germany are able to produce this type of equipment globally. "Our first generation device has been promoted and applied in Wuwei, Hangzhou, Wuhan, Nanjing, Putian and other places. The first Wuwei demonstration device has treated more than 1100 cancer patients in total," Yang Jiancheng said. Researchers have not stopped here. The first generation of products solved the problem of starting from scratch and reached the international advanced level. The second generation product, researchers have set their sights on reducing costs and increasing efficiency. Yang Jiancheng revealed that the second-generation medical heavy ion accelerator has reduced the circumference of the synchronous accelerator to 35 meters through innovative dynamic solutions, while achieving the transition from a single beam single treatment room to a single beam multiple treatment room.
