Double-Cone Ignition (DCI) Scheme: Laser Fusion Experiment Data from SG-II-U

Wei-Min Wang published experimental data from the first integrated tests of the double-cone ignition scheme on the ShenGuang II Upgrade laser facility in 2026. The dataset includes results from experiments using 14 kJ nanosecond and 450 J picosecond laser beams to implode carbon-deuterium shells, achieving a 15.6% heating efficiency and neutron yields up to 6×10^5. Multi-scale simulation data is also provided to analyze the plasma conditions.

Use Cases

• Modeling laser-plasma heating efficiency based on reported density gradient scalelengths and relativistic electron beam divergence.
• Analyzing neutron yield reproducibility and shot-to-shot fluctuation based on the reported 7% variation.
• Simulating plasma compression dynamics based on data from dual compressing cones and the 35 μm separation distance.
• Benchmarking multi-scale simulation codes against experimental results for high-density plasma plateaus.

Strengths

• Includes specific, high-precision experimental results such as a 15.6% heating efficiency and neutron yields up to 6×10^5.
• Reports highly reproducible results with a quantified shot-to-shot fluctuation of only 7%.
• Contains multi-scale simulation data revealing specific physical parameters like a density gradient scalelength of 7.6 μm.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific analytical tasks.
