3D Nuclear Fusion Simulation

Explore a visual D–T fusion toy model with 3D particles, adjustable energy, and collision counts.

What this tool does

This interactive Three.js simulation represents deuterium and tritium particles moving in a confined 3D space. When the simplified collision conditions are met, the scene can show helium and neutron products, a visual flash, and an increased fusion count.

Who this is for

• Students learning the basic idea of a deuterium–tritium fusion reaction
• Educators demonstrating how temperature, density, and confinement affect a toy simulation
• Developers and science enthusiasts exploring interactive particle visualization

How to use this tool

1. Use Show Controls if the parameter panel is hidden.
2. Set initial temperature from 1–500 MK, density from 20–300 particles, fusion barrier from 10–200 E, energy loss from 0–100, and simulation speed from 1×–60×.
3. Choose Reflect or Escape confinement, then click Start Sim.
4. Use Add Energy, Pause, or Reset Sim while watching the 3D view and status readout.
5. Drag to orbit and use the pointer or touch controls to pan and zoom the scene.

Inputs

Inputs are initial temperature, particle density, fusion barrier, energy-loss rate, simulation speed, and wall behavior. These values tune a visual model with hard-coded particle and energy rules; they are not measured plasma or reactor parameters.

Outputs

The scene displays moving deuterium, tritium, helium, and neutron particles. The status panel reports particle count, fusion count, average temperature in MK, and simulation state. There is no energy-balance report, saved run, or data export.

Example use cases

• Show how increasing initial energy can change collision behavior in a toy model
• Compare reflecting walls with escaping particles in an interactive scene
• Introduce D–T reaction products and aggregate simulation counters
