Bio-Quantum Fusion Sensor v4: A Cry4-Graphene Magneto-Chemistry Patch with Passive Radiative Cooling for Real-Time Edge Diagnostics in Tokamak Plasmas
Year: 2025
Type: article
Abstract: Run-away electron events in magnetic-confinement fusion are triggered by nT edge-field jitter that coincides with radical-burst surface chemistry. Conventional Hall probes or IR cameras cannot co-resolve magnetic perturbations and reactive-oxygen species (ROS) on sub-millisecond scales. We present the Bio-Quantum Fusion Sensor (BQFS) v4—a multilayer Cry4-graphene patch only 80 nm thick that detects ΔB≥5nT and ROS concentration change ≥50 ppm at 10 kHz. A new daylight-radiative laminate (SiO₂-PVDF, R⊙=0.95, ε8-13µm=0.97) lowers steady-state patch temperature by an additional 8-12°C, reducing thermoelectric power demand by 75%. Read-out combines Faraday-rotation magneto-optics in Bi:YIG waveguides and graphene Dirac-point shifts induced by Cry4 radical-pair spin states. The downsized Bi₂Te₃ TEC plus CoolWave hydrogel serve only for peak bursts. A reinforcement-learning controller consumes BQFS streams and cuts unplanned quenches by 30% in simulation. CAD, firmware, and data notebooks are released open-source.
