[ Instrument Network Instrument Development ] Recently, the millimeter wave and terahertz technology research team led by the researcher Wang Xiaojie of the Institute of Plasma has successfully developed the first megawatt high-power millimeter-wave steady-state experimental system in China after more than two years of efforts. In the 140GHz gyrotron acceptance test, stable and repeatable high-parameter experimental results were successfully obtained. The output millimeter wave power was 700 kW, the operating time was 3000 seconds, and the technical parameters reached the international advanced level.
High power millimeter wave test platform
High-power millimeter-wave and terahertz technology can be widely used in modern industrial, medical and basic science research fields. Due to national security and core competitiveness, Western developed countries have long imposed technical embargoes on China and embargo on test equipment. Therefore, relying on domestic resources to carry out high-power millimeter wave and terahertz technology is imperative. Funded by the National Key R&D Program “Key Technology for Long Pulse High Power Gyrotron†and the “Key Technology Research for High Power Microwave Drilling†of the Chinese Academy of Sciences Class A Strategic Pilot Science and Technology Project, the research team relies on independent innovation, combined with gyrotron and Millimeter wave transmission equipment multi-case test requirements, technical solution design, material comparison and key process test, successively overcome the millimeter wave complete equipment design theory and processing method, millimeter wave measurement method, millimeter wave source stable operation technology, power supply and cooling A series of key technical problems, such as the integrated design of auxiliary facilities, finally completed the megawatt 140GHz millimeter wave comprehensive research platform. The successful development of the platform provides necessary experimental conditions for deep research, equipment development and application development of high-power millimeter wave and terahertz wave technology, laying a solid technical foundation for the independent development of high-power gyrotron, under extreme conditions. Earth drilling technology research provides disruptive technical support.
Cyclotron full parameter operation output power waveform
In the future, the research team will focus on the research needs of the National 13th Five-Year Plan project “Key Technology Integrated Research Facility for Fusion Reactorsâ€, and focus on the development, testing, aging and simulation of gyrotron and millimeter wave transmission devices under various operating conditions. Experiments, and on this basis, design and build a 170GHz megawatt millimeter wave research platform, and strive to build a higher frequency electron cyclotron experiment system under the condition of fusion reactor.
The development of the megawatt millimeter wave comprehensive research platform has been obtained by Yangzhou Hangrui Electronic Technology Co., Ltd., Hefei Jueneng Electrophysical High Technology Company, Hefei Kezhen Electrophysical Equipment Company, Huangshan Jinyu Power Supply Manufacturing Co., Ltd., Guangzhou Gaochun Energy Saving Technology Co., Ltd. Support from other units.
