According to news on January 7, the Institute of Plasma Physics of the Hefei Research Institute of the Chinese Academy of Sciences recently announced that it has made a major breakthrough in the field of low-temperature projectile preparation and acceleration and successfully developed the first projectile injection system that can operate stably. This achievement marksChina has become the third country after the United States and Russia to master continuous cryogenic projectile injection technology, breaking the long-term monopoly of this technology by a few foreign companies.
The newly developed projectile injection system performs well, with a projectile volume of up to 12 cubic millimeters per round, and a firing frequency that can be flexibly adjusted between 1 and 10 Hz. In addition, the system can also achieve a maximum projectile speed of more than 300 meters/second, and these indicators have reached the international advanced level.
It is understood thatCryogenic pellet injection is an advanced feeding method that cools hydrogen isotope gas into solid ice pellets and then accelerates them into the plasma.This method is of great significance for increasing the density of fuel particles in fusion devices.
It is worth noting that multiple next-generation fusion reactor projects, including the International Thermonuclear Experimental Reactor (ITER), the China Fusion Engineering Experimental Reactor (CFETR) and the European Fusion Demonstration Reactor (EU-DEMO), will use this technology as one of the core feeding methods.
Next, this innovative projectile injection system will be integrated into the fully superconducting non-circular cross-section tokamak device (EAST) to support high-density and high-constraint experimental research.
