Zap Energy has published a groundbreaking paper in Fusion Science and Technology detailing its methodology for measuring net energy gain (Q) in sheared-flow-stabilized Z-pinch fusion plasmas. Their Z-pinch technology is characterized by plasmas that are 100,000 times denser than those in traditional fusion devices like tokamaks, lasting several microseconds longer. The unique approach necessitates specialized techniques to calculate Q, which compares fusion output to input energy. The study focuses on evaluating the triple product—temperature, density, and confinement time—critical for assessing fusion performance across different technologies.
The company’s FuZE-Q device has recently achieved its first plasmas, and ongoing research aims to demonstrate Q > 1. Important distinctions include measuring plasma flow and energy dynamics without conventional temperature detection methods, using both direct and indirect observations to gauge plasma conditions. The paper also emphasizes the significance of input power for stabilizing plasma flow. Given the potential for alpha particles to enhance fusion gain, Zap Energy aims to correlate neutron emissions with plasma conditions, thereby refining its approach to advanced fusion research. Overall, Zap Energy strives to create a low-cost, scalable fusion energy platform, challenging traditional methodologies and moving towards commercial viability.
