Latest Patents

YanHong Guan holds a patent titled "Method for controlling plasma edge fuel particle backflow by powder feedback injection." This patent describes a method that involves measuring a real-time Da value using a visible spectrum diagnostic system. The process includes filtering the measured Da value through a low-pass filter and setting a target Da value. When the actual Da value exceeds the target, an output control voltage signal is calculated. This voltage ultimately determines the lithium powder injection flow rate. The system converts the voltage signal into a sine wave signal, which is then used to inject lithium powder into the fusion device. The injected lithium powder effectively reduces the backflow of fuel particles generated by the interaction between plasma and the wall. This method allows for real-time control of fuel recycling during the plasma discharge process.
