Hefei, December 16 (Reporter Zhao Qiang) Recently, Hefei City, Anhui Province, "systematically promoting the construction of a comprehensive national science center" was successfully selected as a typical experience and practice of the Eighth General Inspection of the State Council, and was praised by the circular. Since Hefei was approved to build a comprehensive national science center in 2017, major projects and high-energy innovation platform construction have made continuous breakthroughs, and the construction of large scientific device concentration areas has been fully launched.

"Our company only moved from R&D to production in 2018, our (proton therapy) main technology comes from large scientific devices, especially the research and development of nuclear fusion devices we are involved in, starting from scratch, the current (treatment system) non-functional detection has been completed, and now we are doing performance testing, and then we have to do clinically related debugging work." Chen Yonghua, deputy general manager of Hefei Zhongke Ion Medical Equipment Technology Co., Ltd., said.

In Hefei Zhongke Ion Medical Technology and Equipment Co., Ltd., a set of professional radiation therapy equipment comes into view. "Patients are like CT scans, receiving proton therapy, which is not long and has few side effects." Chen Yonghua said that the localization of proton therapy equipment developed by his company occupies a smaller footprint and is less costly. At present, the treatment system has "turned over the mountain of technology", and the next step is some procedural work to be done.

According to reports, proton therapy is currently the most cutting-edge technology in the field of cancer treatment. Five years ago, the Hefei Comprehensive National Science Center Superconducting Cyclotroponic Proton Therapy System Project was launched, relying on the original results achieved in the experiment of the all-superconducting tokamak device, at the beginning of this year, the world's most compact superconducting cyclotron proton therapy system officially landed in Hefei.

Chen Yonghua introduced that because there are two major programs for proton therapy, synchrotron and superconducting cyclotron, the diameter of the synchrotron is about ten meters, and the outer diameter of the superconducting cyclotron entity is only 2.5 meters. For this miniaturization, there are great advantages. "In the future, we will also do some work on other miniaturization aspects, such as the optimization of the layout and the superconducting rotating frame."

In addition to proton therapy, in recent years, Hefei has planned to build a large scientific device concentration area with a total area of about 19.2 square kilometers, relying on Science Island and the surrounding Sanshigang Township, with a layout of 11 large scientific devices under construction, construction and pre-research, which is one of the most concentrated areas of large scientific devices in The country.

In the construction site of the CRAFT project, a comprehensive research facility for the main engine of the fusion reactor in the concentration area of hefei large scientific devices, 1/8 of the vacuum chamber and the overall installation experimental platform began to be hoisted, as a major national scientific and technological infrastructure construction "13th Five-Year Plan" priority deployment of large scientific devices, but also the fourth large scientific device of Hefei Comprehensive National Science Center, the current CRAFT project park project has been basically completed, will be delivered and used.

Han Xiaofeng, deputy director of the Major Special Project Office of the Institute of Plasma Physics of the Chinese Academy of Sciences, introduced that if the EAST known as the "artificial small sun" on hefei's "Science Island" is used for experimental physics research, then THE CRAFT here is equivalent to its "upgraded version" and is biased towards engineering technology applications. The ultimate goal of fusion reactor research is to solve human energy problems for commercial applications.

It is reported that since the approval of the Hefei Comprehensive National Science Center, the transfer and transformation of scientific and technological achievements has been accelerated, and the process of transforming industrial advantages into basic research advantages has been accelerating. The total number of scientific research projects (projects) in related fields has exceeded 3,000, the cumulative number of authorized invention patents has exceeded 2,200, 23 achievements have won the National Science and Technology Award, and 4 project achievements have been selected as the top ten progress of Chinese science.
