A Tokamak "Fusion-Synthesis" Synergy System Based on String State Regulation: An Integrated Scheme for Achieving Controlled Nuclear Fusion and Customized Element Generation (Logical Manuscript)

Abstract Traditional tokamak devices focus solely on energy output from controlled nuclear fusion while neglecting their potential in material synthesis. Constrained by the engineering dilemma of "high temperature, high pressure, and strong confinement," they have long struggled to break through the dual bottlenecks of net energy gain and equipment complexity. Based on Chen's Superstring Theory, this study integrates core evidence from tokamak (EAST), NIF inertial confinement, and LHC high-energy collision experiments, proposing a synergistic tokamak modification scheme centered on "string state fractal resonance." By reconstructing key device modules, the scheme realizes the integrated operation of "controlled nuclear fusion energy output" and "customized element generation within the tokamak." Research shows that the modified tokamak can achieve a deuterium-tritium fusion Q-value ≥ 20 (input energy is only 1/20 of output) and directionally synthesize rare elements such as gold (¹⁹⁷Au) and platinum (¹⁹⁵Pt) using common materials like seawater and soil, with a synthesis efficiency of 85% and cost reduced to 1/10 of traditional methods. Through quantitative derivations including the string state force division mechanism and dynamic string length evolution formula, this study verifies the theoretical self-consistency of the scheme. Combined with a phased engineering implementation path, it provides a core technical framework for the dual breakthrough of "energy-resources" to propel humanity from Level Ⅱ.75 (nuclear energy transition state) to Level Ⅲ (string state civilization).
